A long read, but worth reading if you are in this domain: http://msdn.microsoft.com/en-us/library/windows/desktop/aa365247%28v=vs.85%29.aspx.
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.
Instead of working as a manager of a grocery store, you might be interested in managing a food service establishment like a restaurant. Food services managers supervise staff, manage the restaurant's budget, order ingredients and oversee food preparation. The minimum educational requirement is a high school diploma.
