A Cook completes food preparation duties according to sanitation and hygiene standards in order to quickly and accurately fill customer requests. This involves operating all kitchen equipment, cooking restaurant menu items according to recipe and presenting or packaging food items. Cooks may also direct less-experienced workers through the food preparation process. They work directly under kitchen supervisors or general restaurant managers. The majority of Fast Food Cooks are employed at fast food restaurants, but a sizeable portion are employed at gas stations and grocery stores as well.
