A successful businessman flew to Vegas for the weekend to gamble. He lost the shirt off his back, and had nothing left but a quarter and the second half of his round trip ticket, If he could just get to the airport he could get himself home.  So he went out to the front of the casino where there was a cab waiting.  He got in and explained his situation to the cabby.  He promised to send the driver money from home, he offered him his credit card numbers, his drivers license number, his address, etc. but to no avail. The cabby said "If you don't have fifteen dollars, get the hell out of my cab!"

So the businessman was forced to hitchhike to the airport and was barely in time to catch his flight. One year later the businessman, having worked long and hard to regain his financial success, returned to Vegas and this time he won big.

Feeling pretty good about himself, he went out to the front of the casino to get a cab ride back to the airport. Well, who should he see  out there, at the back end of a long line of cabs but his old buddy  who had refused to give him a ride when he was down on his luck. The businessman thought for a moment about how he could make the guy  pay for his lack of charity, and he hit on a plan. The  businessman walked  past his old friend to the front of the line and got into 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 give me a blow job once we get there?" "What? Get the hell out of my cab." The businessman got out and went to the next cab in line where he repeated his question.  Again, he got the reply, "Get out!" He continued down along the long line of cabs, getting into each one and asking the same question 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.
