...after today, I don't think there really is. People tend to think about the decision that are stiff* against your club, but then forget the decisions that go your way and the other club was stiff. There are decision that are missed because the umpire is on the wrong side - it happens and will always happen, and the field umps are not at fault.
Sure umpires have have bad days, but name me one player that hasn't? I reakon the advice Dutchy gives about it is the best "Forget about a poor decision that may have been made against your club and move on. You'll enjoy the match more"
