What should a server do if they notice a guest who appears to be intoxicated?

The appropriate course of action when a server notices a guest who appears to be intoxicated is to monitor their behavior and intervene politely if necessary. This approach is responsible and aligns with safety and legal considerations in the hospitality industry.

By observing the guest's actions and demeanor, the server can assess whether the situation is becoming problematic. If the guest’s behavior suggests a need for intervention, such as becoming overly loud, aggressive, or unsteady, the server should step in with a polite approach, which might include suggesting water or food to help mitigate the effects of alcohol. This strategy not only prioritizes the guest's well-being but also maintains a safe environment for other patrons.

The other options do not promote a responsible approach to serving alcohol. Serving another drink could exacerbate the guest's state, ignoring the situation risks the safety of the intoxicated guest and those around them, and calling security may be necessary in extreme cases but should not be the first response if the situation can be managed more tactfully by the server.
