Did you lose money inside the vending machines ? It is a relevant question i think a lot of people are getting ripped off ...

I did as well. Luckily, there was a man refilling the machine. He said he saw the whole thing and gave me my red bull.

Yup

didn't use the machines, they didn't look very well maintained

Yes i lost the change from a five dollar bill. It gave me the item i purchased but no change back. Needless to say I wasn't very happy about it.

Yes

No, but I didn't use the machines.

Any venting machine anywhere can be a troubled sort.

No I didn't... but I don't think this is a relevant question for a map.
