About 3 weeks ago I was waiting for an elevator with my son and 6 other people. It arrived and out of the blue 2 elderly Asians pushed past me and everyone else to get on first. I barked loudly “hey, you can’t cut the line”! They looked startled, like no one ever called them on their rude behavior before. When the elevator stopped the Asian couple got out and immediately started speaking in that awful sing-song nasally language. Ignorant and unassimilated. Oh, and they act like pigs in the health club too.
I am told to never ever shake a Chinese hand for they publicly and often pick their noses.
I think you hit the nail on the head, unassimilated.
They may not even realize they’re being rude or doing anything wrong. But the rest of us shouldn’t need to change our culture or rules of civility to accommodate them.
