Although vending machine technology has improved over the years, we're still often confronted with the dilemma of paying for an item that gets stuck on its way out. While there is no surefire method to dislodging that trapped snack, how-to site wikiHow suggests that vending machines with door flaps can be used to create a rush of air that can help your food or drink reach its intended destination.

The trick is to get your hands under the flap at the retrieval, push it up, and let it snap back quickly. Repeating this motion a few times can sometimes create enough air to help your snack fall out of place when shaking the machine doesn't work (or you don't want to draw attention by doing it). If you're unsuccessful after a few tries you should instead consider calling for help or a refund. Most vending machines have a contact number around the side that you can use to report a stuck item and receive a refund or learn how you can find someone to help you actually retrieve your purchase. It's great if you can get what you paid for without any intervention, but if you can't your best bet is to ask for help.
