As a policeman, I occasionally work off-duty as a security officer in stores. I was handling crowd control for a going-out-of-business sale, and people were massed around the two cash registers. Determined to establish order, I climbed onto the checkout counter and announced, "Please, I want to organize you into two lines, one for each register. Remember, you all can’t be first—someone has to be second."
A woman in back raised her hand and called out, "I volunteer to be second!"
