A younger member has taken to rocking up and turning our regular weekly two ball into a three. Usually no problem but his lack of pace adds nearly an hour to the round. He's never ready to play, hits the ball a long way but often into the cabbage.Persists in searching when no prospect of success. Some daft habits like waiting until it's his turn to drive before putting on his glove, scrutinising every shot/putt as though the green jacket is at stake. The regular 1330 roll up which he joins is also grumbling. How do you break the news that he needs to speed up?
