5. KinLee Pizza is a popular take out and delivery restaurant that wants to install a system to record orders for pizza and chicken wings. When regular customers call KinLee Pizza on the phone, they are asked their phone number. When the number is typed into a computer, the name, address, and last order date is automatically brought up on the screen. Once the order is taken, the total, including tax and delivery, is calculated. Then the order is given to the kitchen, where the cooks prepare the items. A receipt is printed. Occasionally, special offers (coupons) are printed so the customer can get a discount the next time he or she orders. Customers can pick up phone orders in person, and they get a receipt, a coupon (if any are issued), and their food order. Drivers who make deliveries of phone orders give customers a copy of the receipt and a coupon (if any). Weekly totals are kept for comparison with last year’s performance. Write a summary of business activities for taking an order at KinLee Pizza.
