Lot of people blaming labors and third world people for bad smell, what you will do if your boss is stingy, when he opens his mouth the whole room fills with rotten egg smell. That too he is from states, may be self smell nobody cares. Judging others first with their nationality and TWC etc..... So, nohing to do with education or place you belongs to, it's rather your self decision to be presentable and clean.
