Encounter: 1st visit at 8 Spa with Yumi
Part of the Chinese international facial recognition network - they know a shit-ton more about you than you think.
They have a Wechat group, well actually a few of them. They share pictures of you if you are a bad customer, and share if you are good (overtipper)
It's also how they recruit girls from other spas, and bring in girls from California, NY, Florida and Arizona.
Well for me that has been only time i have asked to leave. And have been to 4 other places since then. To include kings relax and Rongs or li which are all in their circle with no issues.
