Mumbai : Rudest city on Earth

Mumbai - India's crowded commercial centre Mumbai drives the nation's rapid economic growth but is far too busy to say "thank you," making it the world's rudest city, according to a survey.

Reader's Digest performed a survey recently.
Its about the helping tendency and common courtesy.
They performed three experiments:
"door tests" (would anyone hold one open for them?);
"document drops" (who would help them retrieve a pile of "accidentally" dropped papers?); and
"service tests" (which sales clerks would thank them for a purchase?).

These tests were done undercover, ie, no one knew that they are being tested!

And the results say that Mumbai is the rudest while New York is the most helpful and courteous city.
