Which form of identification is accepted when a guest orders alcohol?

A current and valid driver's license is accepted when a guest orders alcohol because it serves as an official form of identification that confirms both age and identity. The driver's license is issued by a government authority, which establishes its validity and reliability in verifying that the individual is of legal drinking age. By providing a driver's license, the server can confidently ensure compliance with laws regulating the sale and consumption of alcohol, helping to maintain responsible practices at the establishment.

In contrast, a school ID does not typically confirm age and is generally not recognized as a valid form of identification for purchasing alcohol. An expired passport is no longer considered valid because it does not represent the current status of the individual, and thus cannot be relied upon to confirm their identity or age accurately. An employee badge, while it may confirm employment, does not serve the purpose of verifying age with respect to alcohol service.
