Reading this I now recall encountering this lad, arrived at a punt which seemed too good to be true at the time, he was waiting outside and said "you waiting for so and so"name I forgot". I replied "who the fcuk are you" he was taken a back with my response. He only said too me she is busy I called her in front of him and she never answered.
Thinking about it now he defo sounds like the same youth, late 20s short and I remember now a convertible BMW round the corner.He was not aggressive towards me or threatening may be because if he had been I think he knew he would get a smack. I was not intimidated by him but can imagine others could be if off guard.
I've seen him around Normanton and I do know he has some not so very nice associates so I'd be carefull before challanging him.
