DH went to the shops last week and was issued a ticket, he got a ticket from the machine and put it on the dashboard. Apparently a ticket wasn't clearly displayed. I appealled and recieved a letter and a picture today which shows the car with the yellow ticket bag stuck on the windscreen, covering where the ticket would have been. I can't prove that DH had a ticket as it flew out of the window as he drove home, but surely the picture should have been taken before the yellow bag was stuck on the windscreen as we can't prove it was underneath it.
