I once flew a (non-indian) airline with a large group of people from india on it (to be honest could have been from some of the neighboring countries too, but looked like the average group of Bangalore engineers) - who stood up and retrieved their coats and carry on from the overhead bins while the plane touched down. A fly around or bumpy landing could really have ruined their day. I was just thinking "that makes sense if you ride on the roof of the bus from the airport home...".

As anecdotal as it gets but still eye opening.
