Which action should a hostess take if a customer exhibits signs of intoxication?

When a customer shows signs of intoxication, the best course of action is to alert the server and a manager. This approach ensures that those who are responsible for the service and well-being of customers can take the necessary steps to handle the situation appropriately.

By notifying the server and a manager, they can monitor the customer more closely, make informed decisions about whether to continue serving them, and implement any necessary safety measures. This procedure is essential not only for the safety of the customer but also for the well-being of other patrons and the establishment's compliance with alcohol service laws.

The other actions listed may not be the most appropriate responses. Serving an intoxicated customer a small drink could worsen the situation, while offering food might not address the immediate need for responsible service and oversight. Contacting the police immediately may be excessive unless the individual poses a threat to themselves or others. Therefore, alerting the server and manager is the most effective and responsible action to take.
