The boy working there told him that they only sold whole heads of lettuce.
The man was insistent that the boy asked his manager about the matter.
Walking into the back room, the boy said to his manager, “Some tosser out there wants to buy a half a head of lettuce.”
As he finished his sentence, he turned to find the man standing right behind him, so he added, “And this gentleman wants to buy the other half.”
The manager approved the deal, and the man went on his way.
Later the manager saw the boy and said, “I was impressed with the way you got yourself out of that situation earlier.
We like people who think on their feet here. Where are you from son?”
“Originally from Essex sir”, the boy replied.
“Why did you leave Essex?”, the manager asked.
The boy answered, “Sir there’s nothing but whores and footballers there.”
“Really?” said the manager. “My wife is from Essex.”
“No shit!” the boy replied. “Who does she play for?”
