Then I figured that I really scored, I was getting ST BJ's in my room for 1000B plus I gave her tuk tuk fare.
You "scored" because you gave 1000baht just for a BJ. Just about anyone would "score" with that offer.
If you want to know what's on offer before you start, don't be afraid to ask "can boomboom?"...the job they are in they are used to it and won't be offended...just don't ask them in front of the other ladies because there are some that boomboom but don't want their coworkers to know
As for asking for extras in Thai...don't think that's a good idea. Think you'll get treated suspiciously if you did.
