An eating establishment may have different types of chefs. Executive chef or chefs de cuisine oversee kitchen operations by managing the work of cooks who actually do meal preparation. They may spend most of their time in administration and do very little in the kitchen. Next in line are sous chefs, who manage cooks, do some meal preparation and report to head chefs. Personal chefs prepare meals in private homes by ordering groceries, serving food and washing dishes. They may be self-employed and have several clients. Private household chefs work full-time for one client, such as a diplomat or top executive who regular entertains as part of his official duties.
