A youngster sets up a lemonade stand before his home, with a sign that says, “All you can drink for a dime.”
Sooner rather than later, a man occurs by, sees the sign, and believes it’s a reasonable plan. He gives the youngster a dime and the youngster gives him a cup.
The man throws it back and says, “Hello, that was very great. I’ll have another.”
According to the youngster, “That will be another dime.”
“Presently stand by a moment,” says the man, “According to your sign ‘all I can drink for a dime.'”
“However, you just had a cup, didn’t you?” asked the youngster.
