With an attitude like that i'm not surprised your car now has two defect notices.
You showed them who's boss???????????
How?
For the 5mins of bs lip you talked they served you with a 2nd defect notice that now you have to sort and take it back to clear. If i was the cop and had you come back to me, i would simply find another defect to put you in your place.
We all know the laws exist, so why have a cry when you get pinned for them. You play the game and roll the dice, your number is bound to come up sooner or later. If you can't deal with it, then keep the car 100% street legal.
