You hit the bull's eye. I am dumb and what is more, I have a what my chinese friend would call a 'dumb face' and I get treated like one. Here is what I gather...you came to the US, got your degree, a good job and made some real money. You went back home to Nepal and the things didn't change - you still get disrespected at Restuarants, shops and at taxi stands. You wonder why this crappy customer service...but it all rolls back to - you guessed it 'poor face'! But I could very well be wrong, after all I m dumb. :)
