I don't see the big mystery cover up you guys are all on about. From what I understand it's a relatively new place (though think there was another spa in same location previous). It came to be during COVID times, not a good time for start-up at all. It's lasted this long, and yet might not have the business to keep multiple girls there all the time. Most of us know SPA's where there's only one MPA working. It's a horrible situation, I hate it, I hate knowing about it, goes without saying the huge security / safety issues and the very last thing anyone of us will do is to tell you what SPA's are doing that. The way I hear some of the interrogation going on, it's as if some were purposely trying to get him to spit that info out.
The photo idea at the SPA I thought at first was a good idea, then I thought about it more, although I have photo's with MPA's, I don't see them letting me take any in a SPA. If he was a boss or a Manager, or someone "important" I think he could get that photo. And he told you he's just a hobby dude so seem's legit he's not getting pic's. He's already told you he's an older gentlemen, buys them food, books some time, hangs around, enjoys their company. I assume they see him as a bit of a father figure that fumbles around (just as we see him), that he's harmless and though tries to help, may not know the best way to go about doing that, as he said, he's not experienced (at SPA business).
You've already heard the SPA can get talent, their not going to be there every day like you see in some top notch places. Do you really want them to be publishing or speaking on the phone, "Ya, we had a couple girls for 6 - 8 hours but we only got one gal for a few hours now, and she popped out to get a bite to eat for a bit." They are not going to tell you that for all the reasons we all know, so you have a decision to make, this naughty guy seems to be able to give a heads up when someone he knows is worthy and available, I think he's lot's of things but I don't think he's a liar, maybe really poor explainer.
KJ or someone must surely know the Boss here, maybe even can help? Can't be their first Rodeo.
