The company that supplies the bikes get around this by renting the bikes to the guys & girls that operating the bikes.
They themselves set their own work schedule. I even had one tell me when it gets slow or he gets to tired and hot, he goes to the movies. I asked him what movies he had seen and he said all of them 2 -3 times LOL. They are basically self-employed.
He took me back from IOA to RPH because I forgot my pass and hotel key up in my room for early entry

I told him I would be right back and needed a ride back asap, He said he would be there and if he had caught a fare to IOA he would turn around and come back empty if he had to.
I came down and he was right there waiting,
I gave him a $20 he pedaled like the wind.
