More important than the golf rules is the etiquette.

Your flight partners can tell you when you break one of the rules, but there is nothing more annoying for other golfers than when you forget to remove your tracks in the bunker or the pitch marks on the green.

And if you have time to be angry and swear at your bad shot, then there is also enough time to shout "Fore!" to warn the group in front when your ball is flying in their direction.
