I have noticed people from Warsaw and western and southern Poland are ok but whats wrong with people from Eatern Poland?.How many people have you met from Eastern Poland? 30, 40, 60, 100, 500?
If you haven't met very many people from Eastern Poland you can't make such generalizations.
Only 1 in 10 thank you for holding the door open for them
I live in Eastern Poland. IMO more than 50% of people say thanks if you hold the door open for them here.
Eastern Poles have some ugly towns and can be quite poor. That makes them hard-nosed brutes but many are just steely and rugged.
How did you come to that conclusion? Towns and countryside are generally poor both in Western and Eastern Poland. It depends much more on the size of the city than the location.
Towns, villages and countryside look very similar from this point of view in whole Poland.
Sandomierz, Przemysl, Jaroslaw, Zamość,Rzeszow
Don't forget Augustów. Cozy small city with beautiful surroundings.
