Silly, old man. Leaning over the till in the convenience shop at a service station. He miscalculated he could use the sales girl for his convenience. When I walked in, he was in the middle of crooning the history of bank notes to her. He stopped when my shadow darkened the note. He said she could pocket the 'clinky' change of two coins. She said a rapid half-thanks and dumped them noisily in the cash register. He could not have missed her sublime slight.
