Kolkata visit 20-27 Aug

As I write something every time I visit Kolkata, here is something this time. I visited old college street area to buy some books on Agriculture. This is probably one of the oldest book sellers street in the world. To my surprise out of say 100 stalls only one shop actually accepts credit cards, forget about any online presence. I was wondering is it sometimes good to do business in a old way or the same way for 100 years? Sat in coffee house for some time, felt nostalgic, it is the same place once used to be place for city's intellectuals. Still has the same charm.

But Amazon didn't come from college street, is it that we have never looked at entrepreneurship, the way the americans looked at?
