As I walked back through the town on my afternoon walk I met someone standing outside a solicitors office trying to get in with some papers in their hand.
"Excuse me," she said, "can you read that?" pointing at the sign on the door. "It says, 'Monday to Thursday 9:00am to 6:00pm, Friday 9:00 to 5:00', but it's not 5:00 o'clock yet is it?"
"No, it's not 5:00 yet," I said, "but it is Saturday!"
"Oh, dear," she said, "How embarrassing."
Puts me in mind of the story a friend used to tell about her mother. Apparently she went to the opticians with her new prescription and asked, "Can you make me a pair of glasses to this prescription?
"No, I'm sorry madam we can't do that."
"Call yourselves an optician," she said.
"No madam, we're the dry cleaners, the optician is next door."
