I had an old Astra estate go into a local garage for an MOT. Came out with a failure.
Windscreen washers not working, (Doh, forgot to put water in them. Ok fair enough)
Cracked number plate
Took the car home and filled the washer resevoir up and then went to look at the number plate and fuck me if it wasn't one of those metal jobbies in perfect condition.
Took the car back and asked to speak to the tester.
He came through and I said, ok I've filled the water up and that's working, but can you tell me where the crack is in the number plate.
Of course he said, went to the car and said "Er, um, oh, but...........ah I was looking at the other car that was being MOT'd at the same time as your and that one had a cracked number plate. No problems, I'll give you a pass now"
Turns out that I knew one of the mechanics there and saw him in the pub the next day and the garage had just had 50 brand new number plates in the same day as my MOT and he was trying to flog new ones on MOT failures.
I should have reported it but didn't bother.
2 things first i would fill the washers and try again and pass (always goes down well with customers) and you cant fail a cracked number plate, part of has to be missing, illedegable or insecure and of cousre wrong size etc
Wish I'd reported the bassa now then, ah well it was about 10 years ago.
