Who told you that? There are spas with trafficked girls, but they are a small percentage of them. I have never been to one. All the spas I have visited, none of the girls were brought here against their will, they too were naive, thinking they could get out of their country and make a good living here, working in a resturant or office. Once here some without work papers and all without english skills found the options limited. They could be
SW, Escort or
Spa girl, or go home. Rather than go home without earning any money, they choose 1 of the 3, lack of options yes, but physically forced no.
They can choose what
spa they work at and what
HJ (hand jobs),
BJ (blowjobs) and
FS (full service). There may be limits on how much service management will allow.">extras they want to provide and how much they want to provide them for. They keep their tip money in most cases (some spas require a percentage), and send it home at regular intervals (when ever they get vacation or days off).
Talk to the girls, most are happy to share their stories of how they came to the US, some won't.
From what I have read (no 1st hand experience here) but sex slaves do not tell you no when you ask for any services, and they do not typically negociate, as they do not want you to make trouble for them. If your girl is not providing
FS or some other service you asked for, and she wants more $$ than you offered, you have a girl who is setting her own rules...
Ask them when they get time off, where they go and such.. Make conversation. A girl who is an unwilling participant, is probably not going to be talking much.
