I don't really understand the mindset of someone who takes mulligans. Even if I play in a charity outing and buy them, I don't use them. I have found that when I do - I hit the same bad shot twice. I think most people do. I also admire anyone who can make a great recovery 2nd shot. Wouldn't you rather do that than a do-over? I'm not talking about playing a provisional here - I'm talking about when a ball is in play, but someone doesn't like it so they hit another one.
nope. some days of golf are just for fun and practice and some days are for money. money days are straight up. do you ever improve your lie in the fairway? wipe mud off of your ball?
