Actually, I am always pleasantly surprised when the SP doesn't ask for payment upfront (even at a 1st visit), shows that she trusts me and feels less transactional. Now, it has happened that I almost left forgetting to pay but she gently reminded me. One time I was even down the hall when I realized I hadn't paid her (and she didn't either, lol) and returned to do so. Now that really felt like a GF experience.
