Polish people are very pushy at the airports, they complain about the baggage, they push with their elbows not allowing you to get near the carousel, they look at what you're wearing and criticize your clothes, they are loud, rude and seam very uncivilized.
Honestly - I've never seen this. Maybe it's because I only fly from Poznan ;)
But actually, now that I think about it - I was on a plane from Rome to Wroclaw that had a very nasty spoiled little bastard on it. I was sleeping (I hate flying, and to be able to sleep on the plane was amazing) when suddenly I heard two very loud bangs. I jumped out of my chair and yelled, then realised that the plane wasn't crashing - only to spot this little thug stamping his feet because he wanted something or other. This went on for the whole flight, I told him to shut up several times, but to no avail.
Of course, when we started to descend for landing, he needed the toilet. And they wouldn't let him go - and I have no problems to admit that I enjoyed every second of his suffering. The plane landed, and they couldn't find the stairs for the plane - which made it even better. And then - when the stairs were found, the door to the terminal was locked. I think he learnt a lot about karma then ;)
