To serve alcohol in a restaurant does the person with liquor license have to be present at all times?

The rules and regulations regarding the presence of a person with a liquor license at all times when alcohol is served in a restaurant vary from state to state. In some states, it is required that a person with a liquor license be present on the premises at all times during the hours of alcohol service. In other states, it may only be required during certain times, such as during peak serving hours. And still, in other states, there may be no such requirement at all. Additionally, some states may have specific requirements for the person with the liquor license, such as requiring them to have a certain level of training or experience in the alcohol industry. It is important to check with the local licensing authority to determine the specific requirements in your state or country.
