So I am relatively new at this.(second week) and on that crazy Tuesday night of the all stars game I had picked up a few good rides and my fair share of 3 buck rides. I was about to call it a night when I got a ping from a few hundred feet from me. Happy couple! Female pax happy to tell me that she just got engaged at dinner and flashed a big rock at me. They were only going 5 blocks so I told them that this ride was on me. They thanked me and when we got to the destination the man thanked me again, with a handshake and a folded bill. Drove 2 blocks before checking to see that he had given me a U. S. Grant (50 bucks). Good deed rewarded.
