13. When Another Player is addressing the ball: this is an important principle in the golf etiquette, as when a player is addressing the ball, you must stand absolutely still (like a statue) just watching the player hit. Any movement, even minimal, is simply unacceptable. As well as talking is also unacceptable. Watch-out not to make noise with your clubs, with your bag or anything else. Just stand still and watch the shot.
14. Gimmies & Mulligans: unless in a friendly game, never "give a shot that matters even if it is really at the limit of remote possibility that the player could miss it. The essence of this Game is to hole the ball, hence, any deviation should be considered only as a special courtesy among friends. Remember that only other players can give you a shot, you cannot pretend it nor ask for it, that would be a breach of the etiquette! Lastly, Mulligans are never allowed.
15. Settling up: always have the exact amount (in cash preferably) needed to settle the game or any bet you may make during the game. Saying, "Do you have change?" or"I will pay you next time is a breach of etiquette.
16. Temperament: never blame out other golfers, the clubs, the weather or even the environment for your shots. Never address to luck (either good or bad) as throughout a whole golf game, good bounces are normally compensated always by bad ones… Never blame another player for reminding and championing the Rules of Golf. Also don’t fall in the attitude to explain why your shot was bad, or good, why today you are playing better or worse than the other day… Don't be so competitive that you forget that golf is a game played competitively for joy. Always play like a gentleman, in demeanor and attitude, because, in golf it is not your score but is your behavior in the court (and the club) that determines the ultimate impression fo your fellow players, friends and club members. Scoring and playing well is what golf is about, but that's not what golf is all about….
17. Final hole: at the end of the game, always shake hands with all the players, congratulate with the winners and thank everybody for their company.
18. Dress Code: we just mention this as the last point being, by itself, a total separate topic !!!
