Generally, I hate parking charges and truly believe that all traffic wardens should rot in hell
I have to disagree. Yes, there are the traffic wardens who take great pleasure in waiting to pounce the minute the motorist's time is up, but I am generally in favour of enforcing parking restrictions, especially when we consider on-road parking controlled by the council.
I believe the majority of on-road parking restrictions are there to facilitate the free flow of traffic, although I'm sure some councils use it as a money-making exercise. However, I regularly see the selfish sods (very often in expensive BMWs and Chelsea tractors) taking liberties at the expense of everyone else and in these cases I'd love to see a keen traffic warden happen to pass by.
