Cheers Michalis, it wasn't too hard. I'd spoken with the guy and arranged a fee (a hot drink, a sandwich and a chocolate bar). I lay opposite him in the street and it was just a case of waiting for the right frame to come along.
I must admit, I did get a few funny looks, I was sprawled on the floor in front of a burger restaurant on a Saturday afternoon. I got paid more attention than my subject, that's for sure.
