Grainy photographs. Limited services. Half hour £200. Moron
Did you read what he wrote? Of course you didn't.
He didn't pay £200 for her pictures: he paid because he shagged her, and he liked her. "Limited services" are of no concern for someone who looks for a GFE: I know it's hard to believe, but most girlfriends don't lick your ass, drink your cum, and shout "PLEASE SPANK ME, CHOKE ME, SPIT ON ME, CUM ALL OVER MY TITS, I'M DYING FOR IT".
If in a city where there's hundreds of escorts a specific girl wants to ask for £200/hh and she finds someone who's willing to pay for it happily (presumably banking on the fact that at that price she won't see many more people on the same day), then the transaction happening makes everybody happy (including me, who wouldn't pay her that amount), and the moron is you who didn't take part in it but still want to judge it.
