Golf is a game that teaches and reinforces respect. There are 3 main aspects to this.
Respect the course-Repair ball marks, rake bunkers after use & leave rakes inside bunkers, fill divots with sand, place all trash in specified containers
Respect fellow golfers-Keep pace with group in front, have the player who is farthest away from the pin hit first on each shot, allow faster players to play through remain quiet and still when fellow players are hitting.
Respect the game-Know and play by the rules of golf and the rules of the golf course you are playing. Don’t be like Rodney Dangerfield in Caddyshack. (Whenever you go out to play, remember that understated is best.)
