Don't worry, this is rare event, and if anything gives a slight warning to those who take girls and LBs they don't know from the street.
If you take a girl from a BKK go-go this is very unlikely to happen, as you know where she works and she will lose her job if she gets complaints like this.
I would only take an LB from the street if I recogniser her or she is with an LB I know.
Kliome i do agree; this is really rare!
My last trip to Thailand, i went to Pattaya (first time in Pattaya), i was so horny, on my second day, i took two LB's in Walking Street and no problem at all that was really nice ....for only 1000Baht (i proposed and they said yes straightaway!!!fine!), this is the photo (not really good!!! sorry) of Lee and Nora
