Responsible Alcohol Service
Taking care of guests also means knowing when to stop serving. Signs of intoxication, how to refuse service respectfully, and never serving minors.
Legal age and ID
In Mexico the legal drinking age is 18. If someone looks young, ask for a valid official ID before serving, politely and without exceptions. Every venue should follow its own policy and local law.
Recognizing intoxication
Signs build gradually. Keep track of what each guest is served and watch for behavior changes, not just drink count.
- Louder speech, slurred words or repeating themselves.
- Loss of coordination: spilling, stumbling.
- Sudden mood swings, aggression or drowsiness.
- Ordering faster or asking for stronger drinks.
Prevent before refusing
Offer water from the start, suggest food and recommend lower-ABV or non-alcoholic options. Slowing the pace naturally avoids awkward situations.
How to refuse service
Do it privately, calmly and without judgment: 'I can't serve you more alcohol tonight, but I can get you water or something to eat.' Tell your manager and teammates so nobody else serves them.
Help them get home safely: offer to call a taxi, a ride-hailing app or a friend. Discourage driving and involve your manager if needed.
