Let's apply our improved understanding of classes to a programming problem. The Bank of Heather wants to open an automatic teller in the Food Heap supermarket. The Food Heap management is concerned about lines at the automatic teller interfering with traffic flow in the market and may want to impose a limit on the number of people allowed to line up at the teller machine. The Bank of Heather people want estimates of how long customers will have to wait in line.
