Changes

Some of them can pleasantly surprise you, for example some gas stations in [[Finland]] that serve fries and self-service salad for only 2 euros. In Poland, fast food like hot dog can cost only about 3 PLN (1 EUR = 3.50 PLN).

On the back of receipts at most 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 and fries.
