I was on a train from Prague-Katowice-Krakow and about halfway through some MASSIVE Polish dude dressed in army gear got on. Shaved head, shovel and generally looked like a mean bastard.
Anyway, after a while of us being shit scared he stood up to get off the train at some god-awful place in the middle of nowhere, a mining area I think, and said to us, in perfect English - "I hope you have a lovely time in our country". He then picked up his stuff, got off the train and trudged off into the distance.
Loved Poland ever since
