You don't truly know someone until you see how they react to their bag of chips getting stuck in a vending machine.
@GaryPoole This explains me. I am always the person who jumps right in and either shifts the machine, checking for sensors first, or goes arm-in to snatch it, if it's low enough, or buy one so that theirs falls too. My husband laughs at me that I keep rescuing people in airports this way.
