An interesting thing Dr. Irani said in his talk. Previously, since India was so populated and goods were somewhat limited, there was no concept of customer service. Except for the very wealthy, people knew there was more demand for their goods than supply, and people just dealt with crappy service. Now that India is getting a middle class (upper middle really) this is starting to change.
It was also confirmed by multiple people that my esteemed colleague spending time in the US was right; Jack Daniels Whisky (Black label to be exact) is the best out there.
Another thing you can buy here that you can't in America; a single cigarette. Good for those who don't want people to know they have a habit :)
