Some old memories. I'm not sure if I remember all this correctly but here goes. Whenever Mr R came in the orange ones came out first the green followed if he had a good run. I could be wrong and not remember correctly, but a Pit Boss who came with Fitz to Reno told me that Mr R was winning big on one of his visits and Fitz brought out some of the CC [Chesterfield Club] chips that he used in Detroit to Pay Mr R. A few spins later Mr R told Fitz he couldn't win with the CC chips and left a big winner. The Pit Boss told me Fitz got more chips, I'm not sure if he said green ones or??
I think I assumed he at that point Fitz bought the green ones ????. Fitz also allowed Mr R after that to send full racks open,not boxes like you picture, back to the cage so they never ran out of Mr R chips again. A very small piece of paper that both Mr R and Security signed went with the open rack.
