Wow, wish I hadn't bothered now.
I found some other feedback elsewhere varying between the girl being one of the best ever and average. It's a cheap punt and I figure count it as information - if the place is good then great, and if not I only lost a few quid.
Get there, go up stairs, the girl is really pushing the extras which are bloody expensive. Without them not much touching or anything really. Anyway really really pushing them, sob story how the parlour takes half the cash on a basic service so she's shagging me for pennies. Oh - and she's annoyed at the confusion over extras, why can't the parlour just tell the customers.
To be honest I wish I'd paid her half the cash, walked and told the parlour I just walked without seeing her and eff off. The girls performance was ok but it was pretty much a nightmare punt, I felt bad for her, felt bad doing pretty much anything really.
So to answer my own question - the reason the parlour don't say is cos they are utter cnuts.
Not going to post details on the girl/location cos I don't want any aggro for her but Im happy to PM anybody who posts on my regional board details.
