I fluff my lies and move my ball from divots, rocks, hardpan, etc ONLY in casual rounds. And then only about 40% of the time. I also play collegiate golf, so obviously i have to play to the rules in the strictest sense in those tournaments.
I just dont see why everyone gets so upset about people bending rules in golf. Sure, if they are doing it when money is on the line or the club championship it's wrong and you have a right to be angry. But golf is just a game to most people. The vast majority of them will never be good enough play in tournaments, (except the ones at the local $15 dollar course) so if fluffing their lies or moving their balls makes the game more enjoyable for them then i don't complain. Also, if someone is picking up your ball in the fairway or doing something else that irks you just politely ask them to stop. Works for me 95% of them time
