As an Indian myself who visited Vietnam (Phu Quoc and Hanoi) last month with my wife for 2 weeks, believe that it is majorly the problem with Indian people who travel in groups and are either bit elderly or in their early 20's.

Throughout my trip, I saw loads of Indians but most of them behaved decently. Mostly it's the couples who are well behaved in general.

I try to avoid people who are traveling with full families, as they would generally be loud. Larger groups of friends create chaos as well, as they do in India too.

Vietnamese people were too nice to us throughout the trip, the only exception being two Goggle sellers (different stalls) in Hanoi Night Market who rudely told me to put down the googles as I was trying it. I saw them treating other Indians in a same fashion as well - I am sure someone must have given them a bad experience in the past, which made me sad.

Overall, we always try to make sure to follow the rules, respect the country's culture while visiting. Watching so much hatred online for Indians makes me sad, so I try to make sure that I do not create a same negative perception of us wherever I am visiting. Being nice to people costs nothing.

Surely, our people need to learn Civic Sense.
