Now I have seen it all. This morning, I saw a car parked on a light controlled pedestrian crossing while the driver went across the road to the shop. Not on the chevrons, which is really quite common, but the kn*bhead had parked right across the crossing itself! The thing is, apart from 20' of yellow lines before the chevrons there is 50 yards of empty and unrestricted parking either side of the crossing.
My brothers phrase, while he was a serving police officer and saw something like that was, "I wish I was driving the company car".
