thai lessons

I was going over some very basic vocabulary words with my thai tutor today and experienced some confusion.

puying-ba = bar girl
me:"what if it's a man, is it putai-ba?"
t: "no, we don't have such a word."
m: "so...you don't just call male bartenders bargirls, do you?"
t:"well, when i say bar girl, i mean prostitute of course"
m:"...and when you mean to say bartender?"
t: "same thing"
m:"...bartender...is the same thing as prostitute?"
t"yes, i would say so"
m:"ok, but what if you happen to tend a bar and you're not a prostitute"
t: "it really doesn't happen that often"

I decided to concede and pretend that this was a gross exaggeration of sorts... I mean, I know prostitution's pretty big here, but I can count about 14 bars on the way to my 5 minute walk to my thai lessons.

Next word: Maw-nuat. massage doctor/ masseuse
My teacher says to me, "Some maw-nuat work like this," and he mimes massaging a persons shoulders, "and some maw-nuat massage like this" and he mimes the action of giving a hand job.

This is funny because I'm getting tutored for the purposes of facilitating my life structure in Mae Sai, where I won't be looking for any maw-nuat, and if I ever so much as referred to one of my students as a "puying-ba," I'd probably be asked to leave and never show my face again. This is probably what comes from enrolling in a school that's catered to teach thai for tourists visiting for pleasure. Oh well. Helps to learn all parts of the language I guess.
