Yes, I've been there mate... I had seen this girl a long time ago before there were proper reviews in Nottingham where she worked with another lady... to be quite frank, they are scammers, moving between Nottingham and Northampton.
Your punt was very similar to mine, used every tactic in the book to waste time, spending up to 10 minutes getting a drink, 10 minutes needing to go to bathroom, comes across as very scatty but I think that's an excuse.
It is a shame as she is a good looking girl, with a great body, said she was half Spanish / English when I visited her.... the services was a short BJ, kissing and she did mount me, but only for a few minutes as it was for an hour booking, "I doubt she does FS in a 30 minute booking"...
Probably one of the worst services I ever experienced of my near 20 years of punting from an English girl.
I believe she has the odd good punt to get a good review, then the next 2 or 3 she scams by wasting time, giving minimum effort etc etc.. then another some what good punt, then back to scamming, very stupid if she wants to maximise her income.
A good looking girl like that, only has to provide a good service and not waste any time, be prompt, professional and prepared for each punter, and she have many regulars and a healthy bank account... my guess drugs has a lot to do with this, and she only cares about getting the next hit, as she came across as extremely disorganised and very scatty, but it could be an act who knows...
Avoid like the plague
