Manage Food Service Staff. Food and beverage managers are often responsible for recruiting, hiring, training, evaluating and terminating food service staff members. Personnel management of restaurant staff requires experience as well as interpersonal skills.
Depending on the size of the restaurant, the general manager may not directly involve themselves in every aspect or task in the restaurant; that means delegation is a key skill for any manager. Extensive experience with restaurant employment and management is helpful to the general manager.
