I know, I know... without rules we'd have chaos. But seriously? This sounds like two friends out to enjoy some golf without backing up the course. Thank you!
If these are handicap rounds, play by the rules (all of them). If these are purely fun rounds, play by the rules that keep the pace up. If this is a money game between the two guys, tell him he can right down whatever number he's feels comfortable with just as long as he knows he lost the hole.
I don't know the level of play here, but the common sense application of the rules should be reflected in the level of play. It doesn't do anybody any good if the guy has to spend 5+ minutes looking, then get in the cart (or worse, walk), drive back to the tee, and then proceed to grind out a 10.
I agree, it is important to know all the rules. It allows for a more informed decision on which ones to ignore.
