Poles "do a lot of hours" on the job but very little work, at least in Poland.
Indeed. Try getting anything from a Polish person from around December 19th-January 10th or during July/August - it's an absolute waste of time. Then we get the incredibly unprofessional "don't know, send an e-mail" attitude on the phone from many businesses. And let's not forget about the fact that many people don't even try and sell products - I've been to one trade fair today, and the utter lack of interest from people working on stands is unbelievable.
Anyway, that same laziness makes them great friends, because they always have plenty of energy for doing things :D
