Throwing bad money after good
I hate vending machines. There, I said it. I probably have a 50% success rate with getting the things that I pay for. I’ll put the money in full of hope, and wait for the item to fall, only to be disappointed when my candy bar gets stuck halfway down the window.
So I feel for this guy, losing his sandwich and having to stare at it through the glass pane. I don’t really agree with his methods of trying to fix the situation. Putting in more money so that the next item will knock through the first just seems like a waste to me. I’d give up and eat an apple.
