A survey has called Mumbai the rudest city in the world, out of leading cities in 35 countries.

The survey states that 'the culture of extending help, expressing gratitude when helped and talking politely are not part of everyday life in Mumbai'.

It adds - Asia, in general, scored low on the chart, with every city on the continent, excepting Hong Kong, finding a place among the bottom 10. New York topped the chart with a score of 80 per cent whereas in Sao Paulo, even miscreants were found saying 'thank you'.

Do you think this is an accurate finding - can Mumbai be the world's rudest city? Or, do you disagree? Which city is ruder, in your opinion? Tell us.
