The owner of KFC wants to use a system to record the orders for the hamburgers. KFC accept the orders via phone calls. When registered customers call KFC on the phone, they are asked their phone number. If the customer is not a registered customer, then a new record is created for the customer. When the phone number is typed into a computer, the name, the email address and the address of customer are automatically brought up on the screen. After taking the order, the total, including tax is calculated. Then the order is given to the cook. A receipt is printed. Sometimes, discount coupons are printed so the customer can get a discount. Carriers who make deliveries give customers a copy of the receipt and a coupon (if there is any). Weekly totals are kept for comparison with last month’s performance.
