The responsibility to act as gatekeeper regarding the community's ability to obtain alcohol in public establishments primarily falls on the alcohol servers themselves. They control access to alcohol, ensuring it is served responsibly and only to those legally permitted to consume it. This role includes checking identification, refusing service to intoxicated or underage patrons, and managing potentially problematic situations related to alcohol consumption

. Additionally, local law enforcement and regulatory agencies, such as the Department of Alcoholic Beverage Control (ABC) in California, play a supporting role by licensing establishments, enforcing alcohol laws, conducting inspections, and responding to violations

. Door hosts or security personnel at venues also contribute by verifying age and identification at entry points, helping maintain compliance with alcohol regulations and creating a safe environment

. In summary, the gatekeeping responsibility is shared but primarily lies with alcohol servers in public establishments, supported by law enforcement and regulatory bodies to ensure legal and safe alcohol service to the community.
