Who is primarily responsible for verifying a customer's age?

The server or seller is primarily responsible for verifying a customer's age because they are the individual directly engaged in the transaction involving the sale of alcohol. It is their duty to ensure compliance with legal age restrictions before serving or selling alcoholic beverages. This accountability is crucial, as they are the frontline staff interacting with customers and are trained to recognize and adhere to age verification policies.

While the owner of the establishment holds overarching responsibility for the establishment's compliance with laws and regulations, it is the server's immediate role during exchanges that makes them pivotal in age verification. The presence of security staff may enhance monitoring of the establishment and can assist in preventing underage drinking, but the primary interaction to ascertain age lies with the server. Other patrons are not responsible for verifying age and do not have any legal obligation or authority to enforce age checks.
