You guys are being a bit hard on the OP. Sounds like a young guy having a good time. I'm surprised that the other dude would get angry about the OP's inability to chip in a few bucks toward cab fare. I mean, if I were having a good time on vacation with some hostel buddies, I'd just give the cabbie a ten or whatever and carry on, instead of picking a fight over the three bucks that someone owed me.
