I wouldn't find any "ladies of the night" interesting enough to want to pay them to talk to me. I would much rather spend a lot less and go and see Prof. Brian Cox on one of his tours. Now there is an interesting guy !
De gustibus non est disputandum. And I never said I paid just to talk to them. Nor did I say I find them more interesting than other people, though some are.
One who took £1.34 million off a punter I talk to frequently on line - but don't pay for the pleasure. Another I had a fling with (free) was the mistress of one of great train robbers.
One I lived with was a friend of Christine Keeler. They both worked in the same club as Barbara Windsor - The Embassy on Bond Street - when she was getting started. Interest is where you find it - if you have the wit to look - and not governed by profession or shallow generalisations - but personality.
