Thinking on your feet

A man in London walked into the produce section of his local Tesco's supermarket and asked to buy half a head of lettuce. The boy working in that department told him that they only sold whole heads of lettuce. The man was insistent that the boy ask the manager about the matter.

Walking into the back room, the boy said to the manager, 

"Some old fool wants to buy a half a head of lettuce."

As he finished his sentence, he turned around to find that the man was standing right behind him, so he quickly added, "and this gentleman kindly offered to buy the other half."

The manager approved the deal and the man went on his way.

Later, the manager said to the boy, "I was impressed with the way you got yourself out of that situation earlier, we like people who can think on their feet here. Where are you from son?"

"New Zealand, sir," the boy replied.

"Why did you leave New Zealand?" the manager asked.

The boy said, "Sir, there's nothing but prostitutes and rugby players there."

"Is that right?" replied the manager," My wife is from New Zealand!"

"Really?" replied the boy, "Who did she play for?"
