Changes

On the back of receipts at all Burger King restaurants in the U.S., there is a toll-free phone number and a blank coupon. Call the number and you will be connected to an automated customer satisfaction poll. At the end of the poll, you will be given a code to enter into the blank spot on the coupon on the back of your receipt. The coupon is good for a free chicken sandwich or small whopper with purchase of a drink or fries. Pick up a large cup outside in the rubbish and refill it inside free of charge. At some Burger King'sKings, your meal is free if they don't give you a receipt (there's no way you can lose!).
