Revenge(报复)

The businessman got in the first cab in the line, "How much for a ride to the airport," he asked? "Fifteen bucks," came the reply. "And how much for you to make out with me on the way?" The taxi driver exclaimed, "What?! Get the hell out of my cab."

The businessman got into the back of each cab in the long line and asked the same questions, with the same result. When he got to his old friend at the back of the line, he got in and asked "How much for a ride to the airport?" The cabby replied "Fifteen bucks." The businessman said "Ok" and off they went. Then, as they drove slowly past the long line of cabs the businessman gave a big smile and thumbs up sign to each driver.
