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.
Cafeteria managers make sure cafeteria workers have the food and supplies they need to serve all the items on the menus. Cafeteria workers frequently check their inventory of food and supplies so they can alert their managers when they notice that they might not have what they need.
