Earlier today, I drove into town to do a bit of shopping.
As the car parks were all full, I left my car in a disabled zone and walked off to the shops.
On my return, I was met by an angry policeman.
"You can't park here you selfish idiot" he shouted, "This is a registered disabled parking bay. For parking here, I'm going to have to write you a ticket."
"But I am disabled" I replied, "I suffer from Alzheimer's."
"Oh yeah" he said sarcastically, "Where's your disability parking badge then?"
"I forgot it" I answered.
