The responsibility to inform the guest they have been cut off and will no longer be allowed to purchase and/or consume alcohol on the premises typically falls on the bartender or the server.When a guest shows signs of intoxication or violates the establishment's policies, the bartenders or servers should be trained to recognize these signals and handle the situation appropriately.
