Traffic wardens are only hated by the small proportion of the population that have got a parking ticket. I know firsthand just how important they are... there were no traffic wardens for nearly a year and in my town the high street was terrible. We had Buses on pavements and several accidents, all because the ****s can't be arsed to walk a few yards so park on the double yellows.
I have never ever seen an empty high street but at least now it's much better we have regular traffic wardens (now council not police of course). I honestly think there should be no excuses, including not waiting for a couple of minutes.
""I think Traffic Wardens should also book people that take up 2 or 3 parking spaces with one car!"" They can and do, and also any parking on pavements is illegal unless in marked bays. Both offences get tickets where I live.
Personally my worst profession is salesmen, specifically car salesman have you ever seen one that comes over genuine? "Yes sir, these (Fiat Puntos) have a good reliability record" - that's what we got from the guy who sold ours!!
