I was watching two A+ players in a money game. Player X racked the balls and then walked away from the table for a bathroom break. Player Y did not like the rack and proceeded to rerack the balls, broke and made the 9 ball on the break. Player X, returning at that point, saw Y's break and called a foul. Y broke down his stick and an aregument ensued. They worked it out and replayed the game. Was it a foul??
