aha, a few saturday's ago (around 4.30pm) I saw a mini van containing traffic wardens driving up crawley grove, park on a junction (double yellow) with archdale road to issue a ticket to a van which did not seem to warrant a ticket. After ticket was placed on windscreen, the warden got back in and the driver drove off whilst on his mobile. The van was white and unmarked. I tried to remember the number plate but of course forgot it. I have no doubt that had I reported it, there would be no record of this vehicle.
