I've had only one bad session at OWC and I immediately told Tian Tian. She apologized and I told her that I wanted a no house fee session the next time I returned or I wasn't coming back. A week later, I got my free session. You are the paying customer, there is no need for you to leave frustrated and come on these boards and vent your anger. It's one thing if you and a girl don't hit it off, but at least leave satisfied. In my case the provider told me I was too big, she was sore, kept blocking me. Finally, it just was not in the cards that day and junior gave up. I tipped but spoke up about my experience. As far as time is concerned, I don't get too hung up on that. If I finish in 40 minutes and I can tell someone is waiting for her, I'll just leave. Either them laying next to me telling me their problems or giving me a lame massage I'd rather be on my way. My last session on Thursday, I went over by 10 minutes. The second pop took a little longer than expected, but my girl stayed with me to the end and by the time I walked out it was 10 minutes past the hour.
