What is one of the responsibilities of a seller-server during their shift?

One of the key responsibilities of a seller-server during their shift is to ensure compliance with alcohol service regulations. This involves understanding and following the laws and guidelines set by local, state, and federal authorities regarding the sale and service of alcoholic beverages. Adhering to these regulations is vital to promote safe drinking practices, prevent underage drinking, and avoid over-serving intoxicated individuals. By focusing on compliance, seller-servers help maintain a responsible drinking environment and uphold the integrity of the establishment.

The other options present practices that do not align with responsible service. Serving only regular customers might imply discrimination or favoritism, while serving customers without restrictions could lead to irresponsible behavior and potential legal issues. Prioritizing profit over safety contradicts the fundamental principles of responsible alcohol service, which emphasize customer well-being and compliance with the law.
