It will all depend on the MP management requirements. One place around here, you had to visit 2-3 times and not do anything to raise suspicion. Then they'd ask you if you wanted a client number and ask you a few questions, not too invasive, "what's your profession, would you like to message directly, how frequent do you plan to visit, how did you hear about us" all fairly easy to answer, but if they are comfortable with answers, a potential of "Have you visited other shops, if so which ones, who did you see, and do you write reviews, if so where?" Communities are fairly small, so if you write reviews and give your handle, or seen somebody at another shop, they'll know.
Others are more invasive, you must supply a photo of and 2 references.
Others are just, client touches provider leg, provider touches under towel and asks what level of massage do you want and how much of a tip will you leave.
There's just no consistency.
For your own safety, you may ask if owners/managers expect special privileges or if they host any exclusive parties. A couple of shops around here had owners that "quality checked" their staff and a couple of others hosted biker "club" parties where their attendance/participation was mandatory.
I've been to a few, Asian and American. I'm not sure what the Asian mentality is. During the visit it seems like if you don't have a problem touching them then you must be safe. I say that because they don't speak English. I have been turned down before, maybe I didn't look the part. Idk
As far as the American girls they talk to you. They ask how old you are, they ask what you do for a living, they have conversations with you. From that they decide how far they'll go, sometimes it may be just a massage depending on the vibe they get.
Thank you. For stating that. I had a massage studio in the state next door. I’m currently looking for another commercial space. Screening is essential. Theres been pushback from members that refuse too. Then I refuse too gotta be safe
