I suppose you can never be sure about any claim. However, I have been punting for 30 years and I think over time you get to know 'the shit from the shinola'. I booked for 3:30 and she texted me at 3:15 saying she was ready. I therefore appeared at 3:20 for my 1/2 hour booking and there was nobody leaving. I stayed, chatting until 4:20 and there was no rush for me to go. She explained that she had enquired at a sauna but didn't like the thought of 6 punters a day. I believe her and hope she sticks to her principles.
Even if all of this was guff, she seemed genuine and I liked her, which is all that counts. She has a really pleasant personality, nice dimples and a smiling demeanour. She was really responsive to my requests and I will return sooner than I can really afford to.
