What should a server do if they suspect a customer has been drinking before arriving at the establishment?

When a server suspects that a customer has been drinking prior to their arrival, the most responsible course of action is to be cautious while serving them and monitor their consumption. This approach is important because it prioritizes the safety and well-being of the customer, allowing the server to keep track of the customer's alcohol intake and assess their behavior.

By monitoring the situation closely, the server can identify any signs of over-intoxication and intervene if necessary to prevent further drinking, ensuring that the customer remains safe. This proactive behavior not only reflects well on the establishment's service standards but also helps in upholding responsible serving practices.

Encouraging the customer to drink more water, while beneficial for hydration, does not address the immediate concern regarding the customer's prior consumption and can inadvertently signal to the customer that it is acceptable to continue drinking. Serving them their usual drinks could suggest a lack of awareness about their condition, and informing a manager could be a step to take if the situation escalates, but it may not be the first immediate response needed if the server can monitor the customer effectively themselves.
