As previously stated by others, this has been a common tactic here over the years and when it happened to me several years ago, I never returned. The Chinese women know this tactic, but I have never had it happen to me at a K-girl spa. The Chinese spas often pay the providers a part of the house fee, and they get to keep their tips. So it is both profitable for the house and the provider. For me, the upsell is a total turnoff and I will leave after the 60 minutes with a $20 tip and never return.
