I prefer the list like at Sandys, at least that way you know whether the extra is value for money for you personally. The problem arises when you have a 1 hour punt and some girls charge double if you have had two services. Most don't, but it does happen.
Well for England and at the price I was impressed on my first visit. But the more I thought about it the more it sucked. Especially all the up-selling in the room. Maybe you get used to it. From a Scottish p.o.v., it stinks.
As far as I am aware, there is no website indication (on the impressive spreadsheets) of what 'extra' costs what. And the list of 'specialties' (which potentially seems the same thing) is extensive:
Check this out -GFE, OWO, CIM, kissing, A Levels, Reverse O, Reverse A, Facials, Fantasies, Mild Dom, 2 girl scene, 2 guys, Couples, foot-worship, face-sitting, toy-show, non smoker.
Most of those should either be included in a flat rate, or require advance notice only, or simply listed as likes or no-do. I go for a shag, not to engage in double-return specialty-booking. It's like having a bird with a clip chart who lingers languorously an inch from your face, and whispers, "kissing is only £10 extra!" and then, as you go for the lips, "and I can make it GFE as well if you want!" Oh, and how much is that? It's the technique I associated with bad street prostitutes. Not good professionals.
I hope they read this and raise their standards instead of relying on lack of competition.
