During a long layover at an airport, I noticed that one business in the main terminal attracted more people than any other. For hours, a steady stream of customers approached with cash in hand, stood in line, made a purchase, and left quickly. All seemed to know exactly what they wanted.
The thriving business was a lottery sales office. Even though the chance of winning the big powerball jackpot was 1 in 146 million, people seemed compelled to spend something and, in almost every case, get nothing.
