While Mumbai is a melting pot of cultures, Delhi is made of community, and we can see these lines quite clearly. An aunty from Punjabi Bagh will be different from a Faridabad aunty or an aunty from Vasant Kunj.
If you are known to do something well, people want to see you do that. But what you choose to do is up to you. After 'Delhi Belly,' I got some 40 scripts - some on the same lines as 'Delhi Belly.' So, I guess people only get stereotyped if they want to.
