Why not the hour? It depends....
I guess if you're 1 pop/30 mins or 2 pops/60 mins it would make sense to go for the hour. Indeed the closer the two rates, the more sense it makes.
However, if you're a one pop charlie like me you have to weigh things up. In my mind I don't attach the same value to all the minutes in the hour and so divide it up into 15 min sections. The first 15 mins is the most exciting as you meet a new bird and get straight into her knickers knowing very little about her. Then you're into fucking and so on, which takes up the 2nd and 3rd 15 min sections. I normally go bang around the 45-50 min mark, so I have a little time to 'come down'. Bit of chit-chat, a shower and away.
So, for a £100/1 hour punt, I value the quarters at £40/£30/£20/£10 (the law of diminishing returns). So for me, £70 would be OK for 30mins. However I feel rushed in a 30 min booking and so am trying to book 45 min meets now as it gives me enough time to do what I want. Tried it for the first time a couple of weeks back and it worked well - I don't really feel as if I lost anything. I was just conscious of having to 'get on with it' at the start ie no idle chatter at the start and so on. I came in, greeted her, paid her and then went straight for a shower as she got the drinks. We were up and running within 5 minutes of me getting there. Popped around the 40 min mark. In fairness we ran over a bit, but that was down to her being in no hurry and wanting to chat. I left, having showered again just short of the hour. Effectively, I value a 45 min punt at £90, although girls often charge £80 where there hour rate is £100.
Assessing it later, it felt like an hour punt even though we went through my routine just a little quicker. Most importantly, I didn't feel rushed.
Her hour charge is £125, half hour is £85 and she charged me £100. As far as I'm concerned, I lost very little but saved £25 which means an extra parlour visit this week (I had a little budget in hand for the month). Going forward I intend to use this option for new girls as it doesn't really feel any different to an hour. Potentially, I'll save £20-30 at each visit, which means I can stick to my monthly budget and enjoy a punt each week.
Each to their own of course - it depends what makes you happy.
