Not sure he's never been there. A few of the things he's said ring true. Thai girls are getting fatter (fattest nation in SE Asia, I think) and fewer attractive girls are available in bars now because of factors like improving economic conditions, more tourists and the power of the Internet and mobile phones. I was there recently and noticed there were a lot of plain faces and dumpy bodies around.
On the other hand, there were dogs around in the mid 90s, it wasn't wall to wall stunners and great cheap service then. The best times were around 1999-2001. Just after the Asian crisis but before the internet and phones got big. 80B to the £, plenty of totty and it was before the Thaksin government started a crackdown on showing.
