Ben owns a grocery store.
He put up a sign on the window.
Tomatoes, 25 cents a piece
or three for a dollar.
The first customer walked in and complained,
"That's not fair!" the young lady declared.
"I should get four tomatoes for a dollar."
Ben apologized and provided the customer,
four tomatoes for a dollar.
The second customer stepped in
and made a big fuss about the sign.
"Your sign can't be right," he said.
"It should be four tomatoes instead of three."
Ben agreed with the old man
and sold him four tomatoes for a dollar.
Ben's friend, Charlie stood near by,
and watched the whole episode.
Charlie pulled Ben aside.
"Aren't you forgetting something?" Charlie asked.
"You should correct the mistake on your sign."
"What mistake?" Ben wondered.
"Before the sign was up," Ben said.
"Customers bought only one tomato."
