A kind stranger once paid a bribe for me and my friend on train at the border between Austria and then-Czechoslovakia without even getting up from the train seats he was lying across, trying to get some sleep.

Literally shifted just enough to shove his hand into his pocket for his wallet and only opened his eyes enough to find the right bill. The only words he spoke was after we thanked him. "It wasn't even 20 bucks." Went back to sleep.
