They also come out at night
Some places yes, some places no. I used to. I've blogged about the drunks, the bouncers and the fast food drop offs. Mind you, after dark we were always thin on the ground, or rather my oppo's still are. The job was to keep people off the restrictions so everyone else could get by safely. We couldn't always be there, though.
Here's a little anecdote from the memory banks; a brand new BMW was parked on double yellows outside a takeaway near my house. I off duty and heading back home from the chip shop on foot. A truck went past in the narrow steet and there's a crunching sound as it is forced to cut in close by another car coming the other way and the truck carves off the beemers wing mirror. The truck carried on as if nothing had happened. I remember thinking at the time; "That'll cost him more than a parking ticket." I don't think insurance companies cough up so readily if you are breaking the law when you have a thump.
