I got caught a couple of times over the years
In my younger days, late 80's I wouldn't have seen it as a problem seeing street girls, and some of them weren't that bad looking in Glasgow, but that changed for me around 1990
Like the op, I was targeted by one of the pimps, who basically was demanding money from you, and most times you had no choice, as he carried a knife and had a pit-bull dog with him, which he threatened to set on me, and other punters as I found out later on
He always found an excuse to talk to you, like how's the weather, which then went on, why are you here, and his 15 year old sister is pregnant, and he is looking for the guy who got here pregnant, now this is where it turns nasty
He thinks Im looking for her, so he going to get the police onto me, but then says let me see what's in your wallet, I have £40 at the most; 4 x £10, he3 decides he will take £30 of my money, which will go to looking after his sister
The dog was used to keep you from, running of, and the knife was for his own protection, in case you decided to fight him
Now I also carry a second wallet, hidden away, in my jacket, and it contained £200, glad he didn't find that one, I returned the next day and spoke to a street girl about what had happened, and she knew who he was, and yes his sister is 15 and works the street, and its not the first time they have done this to other punters, and some of them were going to deal with the pair
She even warned me, not to approach the 15 yr old girl, for the obvious reason, if you pay for sex with here, afterwards, she will blackmail you, and force you to pay more money, even making you go to the atm
after this I stopped going to the rld, and it wasn't long till the police presence in the area increased
