A recent survey shows mumbai to be the world's rudest city. Why? because unlike other cities Mumbai is not trained to say pseudo Thank Yous; and not trained to hold doors open.
The survey was carried out by 2000 journalists, who obviously have more book knowledge than a connection with themselves.
Mumbai isn't clean, or slick, or 1st world; but Mumbai is easily one of the most pleasant & safe cities to live in. Ask any woman who lives in Mumbai and she will immediately tell you "I love how safe I feel here". The ultimate test: "feelings", not actions!
