A cafeteria is a self-service food service location found in institutions like offices and schools. Customers select food from various food stalls or counters and pay at the end of the line. Cafeterias are mainly classified as traditional or free-flow. In a traditional cafeteria, customers move down a straight line of counters selecting food. In a free-flow cafeteria, counters are arranged in various layouts allowing customers to choose which station to visit first to select their food.
