If I understand your question, it is very easy to "No Tip" if you are turned away before anything starts.
I try to get a good understanding of what is going to take place, such as asking "Full body massage?", using gestures and pointing if necessary to communicate. I pay the house fee and my tip comes after the session, based on service. Thus far, I have not had a really bad experience at an
AMP (emphasis on the "A" for Asian). I recall an instance where the provider was attractive and playful, but seemed fearful of going to
HE. I still tipped her for the massage and pleasant company.
On the other hand, my only rip-offs have been at the non-Asian places, where the providers take the house fee, then come back to the room, haggle about upsells and insist on tips in advance; or, even worse, stop the session mid-stream and ask "can you increase that tip?". At that point, I try to make the best of what I have. I do not tip more and I can not call
LE. :-) For several years, I simply have patronized ONLY
AMPs (in most cases). I mean absolutely nothing offensive; it is just a personal preference.
