Double dipping or stealing
Recently went to a spa with walls stopping short from the ceiling Paid one hundred dollars for half hour. She provided the sixty dollar change when I was laying on the table. I tucked it under my clothes on the chair. After the flip and the negotiating, agreed on sixty dollar HJ. After the session was complete I couldn't find the sixty dollars under my clothes to tip for service. I always try and tip at end of service.
No way in hell was I going to grab another sixty from my pockets, knowing my change was missing. I was fortunate she had another client come in and she was partially distracted. She led me out with a bottle of water, but something tells me she knew the game she was playing hoping I would hand her another tip. Stay safe out there.
