So here's how it went down: the mango guy brought me to the parking lot guy, and told him I needed a bike. The parking lot guy brought me to the fisherman, who in this case was the one with the bike. They decided a fair price for me to rent per day, including a little commission for parking lot guy (I can't remember if mango guy got a piece...). Later, when I decided to rent the bike for more days, I made the deal directly with the fisherman, and parking lot guy was none too happy when he saw me on the bike a week or two later. He was entitled to more commission! So we had to go work it out. I ended up hanging out with the mango guy and the fisherman a few more times, but not the P.L. guy.
