4. Tee: only one player at a time is allowed on the tee. While this player is hitting the ball, it is recommended to stay well outside of the teeing area. It would be considered inadmissible if a golfer had to ask you to move out of his/her way anywhere on the course, but especially on the tee, where players are at their maximum concentration. After having hit, make sure to remove the wood (or plastic) tee, if you used it. There is nothing worse than finding a colorful tee pinched into the teeing ground.
Lastly, if you have damaged the grass, ensure to repair your divot properly before leaving.
