Sorry to hear about other peoples experiences.
I think I initially stopped because I wanted to check the damage and then I stayed because I was so stunned by the antique mirror and the total cheek of them. The van was blue and white, a 'Merit' or 'Marit'.
The older guy (Mid 50's ish) was more vocal than the younger one who just stared a lot. I think I was also concerned that I was close to home and they might follow me - which was silly of me really considering he bartered himself down to under a tenner so it would hardly have been worth the petrol!
I didn't want my initial post to be too long, but I did call the police and was informed they don't come out (I even asked for a PCSO instead) the man kept saying 'why do you want to do that' I said because you are claiming I've hit you and I didn't after speaking to the operator he apologised and admitted fault - I wished him a good day and went home to stroke the cat and marvel at another adventure in the wonderful world of Donna!
