Robert Allenby and Michael Tritton
They say that breaking up is hard to do. But not for Tritton, who, part-way through the second round of the 2007 BMW Championship, removed his caddie bib, tossed his yardage book to Allenby and walked off the course. Tritton's resignation took place on the 16th tee (Allenby's seventh of the day), after a disagreement in which the caddie pulled a three wood and Allenby said he thought it was too much club. "He just ignored me, and started walking off the tee," Allenby recounted later. "I said, 'What's wrong?' And then he started whinging at me. For two day's everything's been fine. I really don't know. He said, 'You don't want me to caddie any more. You want me to leave, don't you?' I said, 'No, I don't.' And then he just left." It wasn't the first time Allenby had been jilted. At the '95 British Open at St. Andrews, his caddie, Michael Waite, tossed his bag in fury on the ground mid-round, but finished the 18 before quitting.
