There may be ,if at all such scenario existing in Mumbai as Mr.Syed told but what i feel about the smell of fish is you cannot point to the multicultural nature of Indian society.Come on if a vegetarian neighbourer cannot withstand smell of fish I think one should respect it and should not blame on the Indian multiculture society as Mr.Syed did.Really smell of fish is awful for a vegetarian person.And if non-vegetarians give due respect to their vegetarian neighbours no one can deny them from purchasing flats in any locality.
