A small neighborhood restaurant is staffed by a hostess, three waiters, and three cooks. When guests arrive at the restaurant the hostess seats them and hands out the menu which takes 2 minutes. Then a waiter takes the orders and sends them to the kitchen which takes 4 minutes on average. In the kitchen, it takes an average of 5 minutes before one of the cooks picks the order and starts preparing the meals. Once the cook starts working on the order, it takes an average of 8 minutes to prepare one customer order. When the meals are ready, the waiter brings the food to the table which takes 2 minutes.
