Charlie 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.
"It's not fair!" the young lady declared.
"I should get four tomatoes for a dollar."
Charlie apologized and provided the customer
four tomatoes for a dollar.
The second customer stepped inside the store.
He made a big fuss about the sign.
"Your sign can't be right!" he said.
"It should be four tomatoes, instead of three."
Charlie agreed with the old man.
He sold him four tomatoes for a dollar.
Charlie's friend, Ben stood near by.
He heard both customers complaint.
Ben pulled Charlie aside.
"Aren't you forgetting something?" Ben asked.
"You should correct the window sign."
"What mistake?" Charlie asked.
"Before the sign was up," Charlie said.
"Customers bought only one tomato"
