Make sure before playing a shot or a practice swing that no one is in the position where they could be hit by the club, ball or flying debris.
You do not tee up your ball until it is your turn play.
Do not move, talk or stand close to a player when they are about to play a shot.
Do not play until players in front of you are out of range.
If a ball is lost call the group behind through to save time.
After all players have holed out on the green players should immediately leave the putting green.
If you are holding the group up behind you call them through.
Rake bunkers after you have played your shot. Filling up holes and foot prints which you made.
Replace divots.
Repair pitch marks on the greens. Also repair spike marks made from your golf spikes after the completion of the hole.
Be careful not to make holes in the green with the flag stick. When attending the flag try not to stand close to the hole. Attend flag at arms length.
When taking a practice swing try not to take a divot, especially on the tees.
