What must establishments display if they serve alcohol?

Establishments that serve alcohol are required to display regulations concerning alcohol service and the consequences of underage drinking to promote responsible service and compliance with the law. This requirement aims to inform both staff and patrons about the legal implications of underage drinking, fostering a safer drinking environment and ensuring that establishments adhere to local and state laws. By making these regulations visible, establishments play an active role in preventing underage access to alcohol and educating their patrons about the importance of responsible consumption. This practice not only helps in maintaining legal compliance but also enhances the establishment's commitment to community well-being.

The other choices, while they may provide useful information to patrons or the establishment, do not specifically address the legal and educational requirements that are mandated for serving alcohol.
