I showed my ID covering my name with my thumb, and I showed sally some text I had with other parlors like AS/PP GGR-PH or AL, then I turned off my phone and gave it to Sally and she returned it to me untouched when I leave. I think it's safe for both them and us. We don't want LEO being there just as much as them while we having all the fun, you can never be too careful. Experience is that they just want to be safe, and nobody cares about your identify/info and such.
I didn't see Sara from my past few visit, I think they run 4-5 girls now, and update the one whos working on their website nyallwellnessspa.com and twitter @nyallwellnesss2
