I was watching an interview Chet & Jonathan did with this TV station and Chet said that the Survivor docs told him that he would also have to quit in order to get medical attention for his foot. So Chet decided that he didn't want to quit and just be voted out instead. And he said that he couldn't wait three more days to seek medical attention for his foot. He wanted to be voted out and he said he was honored that people actually wanted him to stay.

But you can quit Survivor ANY time. Just say "Hey Probst. I'm done. Can't go on. I quit." The best thing would have been to have voted out Cirie or Ozzy, waited until they completed their walk of shame and then told Probst he was done. That would have been classic and would have given Chet a memorable exit and a bit of redemption.

Asking people to vote you out IS quitting. It boils down to the same thing. I would argue that Chet didn't even have the balls to quit, he just asked everyone to vote him out so he wouldn't have to. But he quit either way. The whole tribal council was a waste of time.
