We have a rare breed of vending machine here on island...the Kwaj vending machine. There are actually a few types here; the empty/rusty machine and the cigarette/food machine.
The empty/rusty ones are the most severely neglected ones that never seem to get refilled. You put your money in to discover that there is nothing available that you want and when you try to get your money back, the coin return lever is so rusted that it won't engage.
Your choices at this point are to either choose something you really don't want and suffer through it or give it away, or leave your money in there, in essence...give it away. You can try to get a refund from the vendor but that's really more trouble than the dollar you put in there is worth. Actually, I guess in some ways, these machines are like reverse ATM's.
The cigarette/food machines really crack me up. They usually contain your typical vending machine fare; cookies, candy bars and gum but then there is also the tuna and crackers, Cup of Noodles and several brands of cigarettes to choose from as well. I'm not sure why I think this is so funny but it makes me chuckle every time I get something out of those machines.
