A student wants to eat at their university cafeteria. The student identifies themselves to the waiter, either physically or with their ID card. The waiter asks the student what they would like from the menu. After the student selects their food, the waiter serves it to them. The student eats their food, finishes, and cleans up after themselves by arranging furniture and collecting dishes. The waiter then cleans the table. The process is recorded in a database.
