Is there a set of rules or a reference book for golfers that defines golf etiquette?
There is a nice reference book by the author Brigitte Neff entitled "Golf Knigge". It contains very entertaining and amusing anecdotes about the correct way to treat golfers and yourself. The PR manager and communications consultant wrote and edited the book as a sideline. There are now a large number of golf books and sources on golf etiquette. Of course, no golf bag should be without the official golf rules of the German Golf Association. Here you will find everything you need to know from a reference book, albeit not in a very entertaining way, but rather dry and dusty.
