Rudeness is intolerable no matter who it is.
You better never move to India,China ,Russia just to name a few where being rude is a way of life !

I used to live in a neighborhood where the Chinese moved in in droves and it was chaos, most self centered inconsiderate cunts you'll ever see because to them, it's all normal. All the stray cats and even the pigeons all but disappeared from the area. They'd cut lines, stop in the middle of the street to unload packages for three minutes without pulling over a single inch (right before a green light too), casually drop their garbage right out the car window or take a seat on your fender to gab on a cell phone even if you were sitting in your fucking car, hock loogies or blow their snot out of one nostril on the sidewalk in front of you while you're in the middle of hosing it down, etc, etc, etc., all done like nothing, as if proper.
There was no talking or reasoning so it took years of beating the living daylights out of them to deliver the message of American cultural social etiquette until they finally got the hint. Chinese brilliance? I'll tell you right now, it's a fucking myth.
When the Olympics were held in Beijing, China knew the eyes of the world would be upon them and started cracking heads on how they carried themselves regarding all the above which included heft fines for discreetly dropping a turd wherever and whenever the impulse struck them.
