it is NOT because they are active, or attending charity organization or so...who doesnt? other nationalities do morethan them but its just indians are so selfish if they work somewhere they will make that place as indianization, look at the airport if u r in doha international airport u think you are in bombay airport they even speak hindi to everyone, my last vacation i was traveling, the tunisian guy was too pistoff he coulding find someone to speak arabic with and they are english he couding understand them , he asked me is this doha airport or bombay airport. qatar airways u will know it bcz it has a logo otherwise u will think u r flying with indian airline even indian crew speaks hindi to each other in front of passengers! u start hearing hindi from the checkin to the aircraft.

I dont live with example..Reather I prefer to be an example!
