Exercise No. 36: Restaurant Customer Service

Partial Solution 7

g) If the customer does not want to order more, the waitress brings the bill. Here, the order and billing data are needed for the billing system. Once the bill is at the table, the waitress determines the payment method. Customers normally either want to pay cash, in which case the waitress settles the bill immediately, or want to pay with credit card. In the second case, she brings the mobile POS (mobile POS system). In the next step, the customer pays with his credit card and, as a result, the bill is settled. Finally, the customer leaves the restaurant and the process is over.
