Description : If a vending machine accidentally releases 2 of the item you paid for instead of one, is taking the second one considered theft?
Last Answer : It malfunctioned, you can't put it back. I don't see how it could be theft. Looks like it's buy one get one free. What happens just as often is you pay for something and it does not dispense ... have anyone to complain to most of the time so usually you end up losing your money. It all averages out.
