I feel sorry for them really.
The dream of doing Police work in interesting, far-off locations being crushed by the realisation that the trade you've just joined is being cut by 50%. On top of that, because OC Sec is a Rock (and by defult someone who hates Snowdrops) he's making you keep the station tidy (something else bored Rocks seem to like)by moving all those messy badly parked cars.
As for the tax disc thing, if the car is parked on a patch outside the fence there is nothing more they can really do than you or I.
ps, I loved it when a 'baton instructor' copper came into my clothing stores to ask for some 'black combats'.
Me - "Why do you think you need them?"
SWAT team member Max - "Because of Health and Safety".
Me- "How so?"
STMM - "Because if someone enters a lesson when I'm teaching they'll know who the instructor is."
Me - "You'll be the one out the front."
