Hey man, I can't speak for Poland here. But I can speak for the USA and I recently stayed in Colombia, south america for a while. Don't be afraid of when people say "oh that works in the (USA, Canada, Czech, etc) it wouldn't work here...". Truth is, even in those countries the people say the outlandish one night stand stuff "would never work here man". People say that everywhere, it's just an excuse that people tend to make up to not try.
There have been several things that I have thought would never ever work in the USA.. but low and behold, it turns out I can push the envelope a little more than I thought.
The lesson here is to push it man, you'll soon discover there is a ton of shit you can get away with, if you come from the right frame and mentality
Good luck man!
