The girls in view of the CCTV could be a set up!
I know this sounds a bit far fetched but many years ago when I'd not long started driving, I was lost in London late one night. I pulled up at a bus stop and asked a lonesome woman directions. She didn't have a clue, so I thanked her anyway and I drove off. Immediately a parked car near the bus stop put it's headlights on and pulled off behind me driving up my arse......On came the blue lights and sirens!! WTF! I'm not speeding or anything, I don't even think there were any bus stop or bus lane restritions even thought of back then, let alone implemented and enforcable.
I pulled over and waited thinking they'd whizz pass me onto their emergency. I was wrong. Ultimately, 2 police officers approached either side of my vehicle. The one on my side tapped the window for me to wind down my window, (no electric windows back then in your average car!). The other copper just opened the passenger door. Usual array of questions followed. They asked what I'd said to the woman. "Asking directions", I replied. A brief radio communication later and a wave to the woman by one of the coppers and I was told it was OK to get on my way. They did explain I was in a red light district and that was the reason for stopping me. As my knowledge of London grew, I later realised that I was actually in Pancras Road, (runs up the side of Kings Cross Station, alongside the railway arches).
Call me naive, but my contact/knowledge of prostitutes was almost zero back then, other than what I'd seen on a pirated VHS copy of Lemon Popsicle. This odd incident did teach me though to be ultra aware of my surroundings; especially when I frequented this same area many years later for the occasional £10 blowjob in the car, parked up in the side streets not far from that same bus stop. Mind you, you had a choice of up to a dozen girls back then, including some mature, decent looking women that "took their job seriously" so to say and dressed up to look the part, like the EE girls of today that I've seen down Ilford Lane.
