In a recent game, one of the players told me that failing to remove a ball from the hole (holed out ball) before the next person holed out would result in a penalty stroke.

I have checked the rules and I cannot find any mention of this...in fact I would suspect that as the ball has been holed it is "out of play" and therefore cannot possibly cause a penalty...after all, what harm can it do !

Has anyone heard of this before and is there ANY truth to the tale?
