Spitting in Calcutta

I am interested in researching spitting cultures around Asia (see Protected content ) and want to know about public spitting in Calcutta, what kind and who does it?

Please discuss here but if you have the time I would be grateful if you could also fill in my short survey. I'll be happy to post the results here when it is completed: Protected content

If you like the survey please tweet it to friends, colleagues etc.
