Candy Bar

You've ruined this idea, why not another?

You're hungry, but you're stuck at work, or school, or don't have time to go get a real meal. Or maybe you just want something sweet. Luckily, you've got some change and access to a vending machine. It's snack time. You insert your money, punch in the code, and get ready for that bar of sweetness to drop. But it doesn't.
