Shop

The shopkeeper stood behind the counter. He was reading a novel to pass the time.
He was aware there was a customer waiting, but he was at a really tense part of the story and couldn't put the book down.
The customer coughed.
The shopkeeper ignored it.
"Excuse me!" the customer blurted out.
Still no response.
The shopkeeper was irritated. Couldn't they see he was busy?
"Well, I never." The customer turned and left the shop.
The shopkeeper read his novel until he was finished and didn't serve a single customer all afternoon.
