Chennai gives me nighamares. In 2002 I was working there for few months 9 to be specific. Before that I had never visited Chennai or south . As soon as I got in taxi from airport I can still remember how it was, so much pollution , noise and otherwise. when I reached guest house the water was so salty that I threw up as soon as I put in the mouth ...In chennai tankers supply water, and mineral water is used for drinking. may be some parts have its own supply I dont know but I used to be in egmore heart of city.. Traffic was so chaotic and being not from chennai language was biggest barrier. The list is endless what to say about chennai. However at some point I had started liking the place too but overall I was completely out of place..
