I think what they do now is just open it up and present it as a regular run of the mill massage place, then after a while secretly sell it to someone else who then turns it into a rub and tug or more, add CCTV and puts locks on the doors where they control the foot traffic. Just speculation but it makes good business sense where they don't need to raise suspicion if they were to apply for a business license in the first place. That's how Great Massage in Concord came to be ( RIP). It was a mom and pop place as was the San Leandro Health Center, it was run by an elderly lady about seven eight years ago when I had just dropped by the former video store next to it, now it's a facade for all things naughty.
