Updated November 8, 2026. This article was written on May 3, 2024, the Friday before Cinco de Mayo, and draws on ABC’s release from that day. Figures quoted are ABC’s 2024 figures; check current sources before reusing them. It is general information, not legal advice.
A Sunday holiday with a Friday start
Cinco de Mayo fell on a Sunday in 2024, which meant many restaurants and bars planned for a three-day weekend of celebrations. On Friday, May 3, the California Department of Alcoholic Beverage Control (ABC) reminded the public to celebrate Cinco de Mayo responsibly, and reminded licensees to check IDs carefully and not over-serve patrons.
“ABC licensees can help keep communities safe by checking IDs and ensuring customers are not over-served,” ABC Director Joseph McCullough said in the release. “Let’s all do our part to keep these celebrations safe this holiday.”
The release also included something servers can use directly on the floor: a plain-language explanation of what counts as one drink and how quickly drinks add up. This article builds a service plan around that information. Our St. Patrick’s Day guide covers all-day event staffing in more detail; this one focuses on the arithmetic behind the drinks.
What ABC said about standard drinks
Citing the California Driver Handbook, ABC’s release said one drink is based on 1.5 ounces of liquor at 40 percent alcohol, 12 ounces of beer at 4.5 percent alcohol, or a 5-ounce glass of wine at 12 percent alcohol. ABC also said it takes two drinks consumed within one hour by a woman between 120 and 160 pounds, and three drinks by a man between 180 and 220 pounds, to be over the legal limit of .08 percent, and that blood alcohol content lowers at a rate of .01 percent for every 40 minutes between drinks.
ABC reminded the public that it is illegal for anyone 21 or older to drive with a blood alcohol content of .08 percent or higher, and said those charged with a first-time DUI face an average of $13,500 in fines and penalties, as well as a suspended license.
These figures are general estimates, and individuals vary. But they give servers a common language for thinking about how much a guest has had.
Why holiday drinks are rarely “one drink”
The standard drink definitions matter because many holiday menu items contain more than one. Consider a few common examples:
- A large margarita. A margarita made with 3 ounces of tequila contains roughly two standard drinks of liquor before counting any orange liqueur. A 20-ounce specialty margarita can contain more.
- A craft beer. A 16-ounce pint of beer at 7 or 8 percent alcohol contains well over one standard drink, compared with a 12-ounce beer at 4.5 percent.
- A pitcher. A 60-ounce pitcher of beer shared among three friends is roughly five standard drinks at 4.5 percent alcohol, or about 1.7 drinks each, before the next pitcher arrives.
- A bucket special. A bucket of five or six beers looks like one order but represents several drinks.
- A shot alongside a beer. A combo special counts as two drinks, not one.
Servers do not need to calculate exact alcohol content for every guest. But knowing that a large margarita may be two or more drinks helps them pace service and recognize when a guest is moving faster than they realize.
Menu choices that support responsible service
Holiday menus can be festive without encouraging overconsumption. Some practical approaches:
- Offer a standard-size margarita alongside any large specialty drink, and price it so guests are not pushed toward the larger size.
- List pour sizes or alcohol content for strong beers and specialty cocktails.
- Feature food prominently. Tacos, appetizers, and shareable plates slow drinking and give servers a natural reason to check in.
- Offer nonalcoholic options such as agua fresca, nonalcoholic margaritas, and sodas. Our nonalcoholic drinks guide has more ideas.
- Avoid promotions that reward speed, such as specials that end in a short window or drinks priced to be ordered several at a time.
Counting rounds on a busy floor
On a crowded holiday afternoon, it is easy to lose track. A few habits help servers and bartenders keep count:
Track by guest, not by table
A table that orders four pitchers might include one guest who is drinking most of them. Servers who note who is drinking what can spot that guest.
Watch the pace
The release’s guidance that blood alcohol content falls about .01 percent every 40 minutes is a reminder that the body processes alcohol slowly. A guest who orders a drink every 20 minutes is accumulating alcohol much faster than they are processing it.
Use the point-of-sale system
Many systems show the number of drinks ordered on a check. A quick glance before the next round tells a server how much the table has had.
Hand off clearly
When servers change shifts during a long holiday, the outgoing server should tell the incoming server about any guests who need watching.
Checking IDs on a holiday weekend
ABC’s release emphasized ID checks. Holiday weekends bring larger groups, more first-time guests, and more young adults. Selling or furnishing alcohol to anyone under 21 is prohibited by Business and Professions Code section 25658. Servers should check ID according to house policy, and watch for adults passing drinks to younger companions, especially when drinks are served by the pitcher or bucket.
Recognizing intoxication early
Serving alcohol to an obviously intoxicated person is prohibited by section 25602. The standard drink figures are useful because they help servers anticipate when a guest might be approaching that point, rather than waiting for obvious signs.
Early signs can include louder speech, faster drinking, and a change in mood. Later signs include slurred speech, loss of coordination, and difficulty following a conversation. Servers who notice early signs can slow service, offer food and water, and check in, which often prevents the need for a refusal later.
When a refusal is needed
If a guest shows obvious signs of intoxication, stop service. Keep the conversation private and calm, offer water and food, and involve a manager if the guest objects. A refusal is easier when the server can point to a clear policy and the manager backs it up.
Getting guests home
ABC strongly encouraged anyone drinking to designate a sober driver or use alternate transportation. Venues can help by:
- Posting rideshare and taxi information near the exit.
- Offering free nonalcoholic drinks to designated drivers.
- Asking groups at the start of the visit who is driving.
- Helping any guest who appears impaired arrange a ride.
A short preshift briefing
Before each holiday shift, managers can cover a few points in five minutes:
- Today’s specials and how many standard drinks each contains.
- The house ID policy and who to call with questions.
- How to slow service and when to involve a manager.
- Designated driver offers and ride options.
- Who is handling the door and the patio.
A scenario at the bar
At 4 p.m. on Saturday, a guest orders a second large margarita. The bartender knows from the preshift briefing that each contains roughly two standard drinks. The guest arrived an hour ago. The bartender suggests a plate of tacos and a glass of water with the next drink, and checks back 20 minutes later. The guest agrees to slow down, and the afternoon continues without a problem.
Menu design that makes counting easier
A holiday menu can do much of the counting work before a guest ever orders. Owners who plan Cinco de Mayo specials can build responsibility into the menu itself:
- List pour sizes. Printing “1.5 oz tequila” or “2 oz tequila” next to each cocktail helps servers and guests understand what a drink contains.
- Avoid oversized novelty drinks. Giant goblets and “bucket” margaritas can hold several standard drinks in one glass, which makes it hard for servers to track how much a guest has consumed.
- Price food attractively. Discounted tacos, chips and salsa, or shared platters encourage guests to eat while they drink.
- Feature zero-proof options. A house agua fresca, a virgin paloma, or a nonalcoholic beer gives designated drivers and pacing guests a festive choice.
- Be cautious with promotions. Discounts and specials should comply with ABC rules and local conditions on the license. When in doubt, check with your local ABC district office.
Preshift huddle for the holiday
A five-minute meeting before doors open sets expectations for the whole team. Cover who checks IDs at the door, how servers will track rounds for large tables, which manager makes cutoff decisions, and what to do if a guest becomes ill or aggressive. Remind staff that any server can slow or stop service, and that managers will support those decisions. Repeat the huddle for the evening shift if staff change midday.
After the party: a quick debrief
The day after a big holiday is a good time to learn. Managers can ask a few questions while memories are fresh: Did any tables get ahead of the kitchen? Were refusals handled smoothly? Did the door team see many fake or borrowed IDs? Did any guest need a ride or medical help? Writing short notes now makes the next holiday, from Memorial Day to the Fourth of July, easier to plan.
Frequently asked questions
Is a large margarita one drink?
Not by the standard ABC cited. One drink is based on 1.5 ounces of liquor at 40 percent alcohol, so a margarita with more liquor counts as more than one drink.
Can servers rely on the weight-based estimates?
They are general guidance from the California Driver Handbook, and individuals vary. Servers should use them to understand pace, not to judge a specific guest’s blood alcohol content.
Does a nonalcoholic option need to be on the menu?
No law requires it, but nonalcoholic options make it easier for guests to pace themselves and for designated drivers to enjoy the celebration.
