I had a off duty copper come into work and try to book me for driving in a manner that creates undue noise.
I had driven off from work like a bloody granny get back from the shop and in the shed start eating my lunch and this guy comes in. HIM: You know who we work for he says , whilst flipping his badge.
ME: Yeah what now

HIM: I should book you for the way you drove off here 15minutes ago
ME: Umm yeah what for mate
HIM: The way you were driving was agressive and loud
ME: I didnt drive in any such manner, I didnt not even so much as chirp a tyre, I didn't break the speed limit at all, I didnt accelerate eraticly
HIM: Well I saw you, and I should defect you for your exuast as well.
ME: Good luck mate its tested under the DB rating, Its a owner certified mod, and its passed a emmisions test
HIM: Ummm well it isnt factory piping its heaps bigger
Me: Nup there are dual 2 1/4 inch pipes under there just like stock just with different mufflers.
HIM: your wheels are way to big
ME: Nup 18x8's were standard on the pursuit250's and even if they werent I can still go one inch bigger and increase the track by up to 1 inch as well meaning half an inch on each tyre. Before I would need an engineers report
Him: Your ute sits to low as well
Me: here we go, look mate you can get your roller under it as proven many a time before. Would you like an engineers report just to prove all this to you as I can have one in the station by tomorrow if you like.
HIM: No need to be like that I'm just warning you if I see you driving like that again I'll throw the book at you.
ME: Whats your name and badge number sir ?
Him: Gives details
ME: Enjoy you day mate and if you dont mind I'm finishing my lunch before it gets cold.
Half the time I think the dodgy coppers try to get you to admit to having a defect that doesnt exist so they can give you a ticket for it knowing you wont challenge it.

Not this little black duck. I'll cop it sweet on the chin if deserved but never for some thing I didnt do or isnt correct.

Funny you have to be on your full licence to be in the Hwy patrol.
