What is the most frustrating thing your partner(s) have done?

[Jurassic Referee]

You're in a no-win situation, Tomegun. With guys like this, I think that the best thing that you can do is just smile, nod your head, don't say anything to him, and let everything that he says go in one ear and out the other. No use getting mad; that might affect your game and you don't want that. Just hope that you don't get stuck with him again.
