Most immigrants strive to fit in with those aspects of the host culture that they appreciate. Every immigrant to the US changes their behavior: don't litter, obey traffic rules, stand in the queue, it's okay to smile at strangers etc because they see that everyone else is doing it and it makes life better.

However, this article is about tourists who have no stake in fitting in and will be on a plane back home in a few days.

The Indians outside of India are most probably not tourists. India is yet to gain Chinese level wealth. Unfortunately a trip to India would tarnish your image of us. It's a crowded third world country with third world facilities.
