I once annoyed a copper knocking (i say knocking, banging loudly with his foot or hitting stick) on my door-
Excuse me sir is that your car parked outside your house?
The one parked illegally officer?
Yes.
No that's yours.
Not the police car, the one in front of it.
Nope.
Well it's parked in front of your house...
So is your police car, but that's not mine either, unless that's what my tax bought.
Just tell me are you the owner of the blue Honda, it's registered to number 19.
You've knocked on number 9, and thanks for letting me know who's that car is, it steals my parking place.
It's illegal to park ther... Oh well we'll go and see number 19, bit of advice, there's no need to be flippant to policemen.
I was out till 5am, you just woke me up. I'm grumpy now.
The older policeman with him had a smile on him so I guessed it was a new recruit being chaperoned.
Turns out number 19 didn't like taxing their Honda, parking legally, slowing it down for speed cameras.
