Kyle-perhaps I made it seem too much like I just go around the course telling new golfers how they should act. I do not. If they take a big divot, I will either pick up the divot for them, of fill the divot with sand, whichever is easiest, and what the course wants. If they hit a nice high shot into the green, usually I will fix the mark (if they don't) and then let them know that it is customary to fix marks on the green. But I do not go around trying to boss around new golfers, I understand that those sorts of things become major factors in them leaving as well, in some ways even contributing to the intimidation.
--But the point is, educated golfers (and people in general) will be more comfortable going somewhere if they at least know the basics of how to act. I have an idea that just about any experienced player would be intimidated if they were to be invited to play Augusta or Pine Valley, just because they do not know what is expected there. The same is true for the beginner at the local golf club.
