Input: Was traveling through Europe a while ago and I needed to get some cash out from the atm, the credit card I had charged  a higher withdraw fee than my friends' card, so I transferred them (100euro) and asked them to get it out from the atm. The atm had an error and it took the money from my friend's account but didn't give out any cash, my friend tried it again and it worked the second time around. My friend insists I owe them 100 more euro. The argument they are using is that they did me a favor, without them doing me that favor they wouldn't be down money, I'm saying they need to talk to the bank, and if the bank doesn't give them the money then I will give them the 100 euros...
