Always Check the Receipt
One of the first things people do after receiving their order is toss out the receipt. Do not do this! If you read the fine print carefully, you’ll find a link to a survey. If you fill it in and jot down the validation code, you can score all sorts of free stuff the next time you visit McDonald’s.
Some of those free items include a free ice cream cone, a free apple pie, and even free french fries. If you find a receipt on the ground, and if you’re a starving college student or millennial who hasn’t saved enough money to buy their own place, make use of those surveys to score a free side dish to your meal.
