And yes, there is an interesting point that I forgot to mention before. Two of the kids were Swedish and the other two Indo-Brits. Apparently, 3 of them - both the Indian siblings and the Swedish girl had to show IDs even though they were with their parents to start with. Interestingly, Sven, the 18 year old Swedish lad was not asked! He does not look older than his age as far as I can tell and so I wonder if this is some form of subconcious discrimination?
