I remember with those old vending machines with the circular rings - sometimes they get hung up. Someone buys a packet of chips but it just hangs on, and that someone misses out. Passers-by sees it and they try to get two packet of chips, so they pay for another packet of chips. Of course - now two packets of chips are stuck. Sometimes this can go up to three or four. What I used to do when I see it is spend a minute looking at it, buy a packet of chip in such a way that all two, three or four packs fall down, then hand out the "free" ones to people watching. :) Now that vending machine technology has improved, I do not see many of these "opportunities" anymore, but sometimes you see the odd one where the door is jammed and there are several packets of chips behind it. I get out my metal ruler and fix up the door, then pick the packets of chips up. I was getting chips that aren't "mine", but at the time I really hoped I was doing a public service when I was fiddling with those vending machines... (there's a little show-off element to it. ok, more than a little. :) )
