Just to add my two cents - I arranged an appointment with Model Delia about a month ago and summoned to a strange Edwardian building off the Euston road - little did I know that I had actually been corresponding with her madam, that the place was a dingy brothel, and Model Delia was nowhere to be seen. I was then given the choice of two girls presented to me (which is a process that feels really fucking dehumanising and weird). That said, I picked one, who gave her name as 'Minnie' (though she told me in hushed tones at the end that her name was Tulip O'neill) who was, from what I could discern through the murky half-light, quite attractive, but who was as nutty as a mixed nut selection, guffawing at her own jokes, and i think on the influence of a whole bag of coke. Luckily I'd only booked 30 mins, after which I scarpered. Anyway, the moral of the story is aim for someone independent - even if that means paying a bit extra.
