Beautiful tour of the city of Bangkok, Thailand mate! Thanks for sharing & don't cross the streets there because a RU-vidr was seriously hurt by one of that dangerous traffic there recently! Glad he's doing okay and wasn't Killed!
I saw the sign for Sugar Club, so I did a google search for Sugar Club Bangkok and it said Sukhimvit 11. That's probably where most of the video was taken. I always figure out locations by looking at shops and buildings in the background.
It's most likely a non lady boy club. So they're checking the girls ID to make sure they're not ladyboys. If you see clubs doing this, that is a good club for no ladyboys.
