i find that 9/10 times 30mins is indeed 30mins. Sometimes its a little less, sometimes a little more. I dont really mind as long as i had a good time. One time i do remember meeting a girl who was all about getting punters in and out quickly. I was only there for about 15mins when i was told time was up. Ill say that this girl also didnt allow reviews. Leason learned and all that.
