The young man working in the produce department of a large grocery store was approached by a customer who said he wanted to buy half a head of lettuce.

The young man was taken aback somewhat and indicated he would have to check with the store manager.

So the produce clerk went to the store manager's office for instruction. He stood in the doorway of the office and said, "There's some dumb-head out here who wants to buy just half a head of lettuce."

Then, noticing that the customer had come up behind him, he added, "And this gentleman wants to buy the other half."
