There was a traffic warden afew years ago who was going to do the very same thing where the disabled badge slipped a little and would require a bit of leaning over to see the time.
You could see the time if you took the trouble to try.
The warden was about to write a ticket until I shamed him on the street in front of everyone.
I told him he was going to give a fine to a disabled person despite him being able to see the ticket. I said that it could be a lot of money for someone who is disabled.
He got out of there sharpish. He actually looked embarrassed, like he had a conscience.
