The SmаrtDiner system аllоws restаurant custоmers tо order food from a digital tablet at their table. Each Order contains multiple Menu Items (like burgers, sodas, or salads). The system sends the order to the Kitchen Printer, which prints a paper ticket for the chefs. When the meal is finished, the Waiter generates a Bill for the customer to pay. The system also tracks the Ingredients used to update the kitchen’s Inventory. Which of the following would NOT be an appropriate Class for a Class Diagram of the SmartDiner system?
