Should have posted the sob story from the OP into a post it note and then stuck it to your car window. Parking Plod might have let you off.
I'll try that, although it wasn't a traffic warden so maybe the CCTV camera wouldn't be able to focus on a post it note. I'll go for an A0 print then it should be able to see it.
I'll print it on the roof of the car in fact that would remove any worry they won't see it.
