I mean, even you can get a bit rude sometimes. Just like I can, and I think that's alright.
Ditto.... and as for the Americans being rude... depends on the person again, etc etc. I'm from the North and we are much more direct & to the point than the Southern folks. I found the Polish people to be very nice in almost every interaction I've had. Wasn't wild about the time I spent in Britain, frankly, I found the shop keepers rude & lots of people rude. Didn't care for Vienna, either, or any other places in Austria. Same reason.
