TAT have targeted the Asian markets for the last few years hence the increase in Indians etc. The bars don't like them as they don't buy a drink and think the barfine is for the girl for all of them for all night...

I stayed at the Siam Bayview in Patts last year and when we got in the lift a Thai girl was on the floor in tears; my GF and I took her to our room and calmed her down and got her story.
She'd been picked up by one Indian who took her back to his Loom where 5 friends were waiting and they repeatedly abused this girl all night then kicked her out with no money. We offered to get the BIB but the girl said they would just arrest her. I did complain to the management who said they were helpless; the receptionist told me privately later that the deals from TAT allowed them to stay 4 to a room.
I don't know about anywhere else in LoS but they are definetely not liked in Pattaya.

I noticed a few weeks back that there were a fair few Africans wandering about but they were not tourists.
