OP, one does not have to be able to consistently execute a proper shot to be able to see someone else doing something wrong. Not saying you're getting proper advice, but I don't think saying "well you just shanked it!" is anymore proper. I dunno. I do understand that it can get old, if you've got your own thing, though.
The only people that bother me are the ones that will take a swing, shank, and look at their glove like it did something wrong, or kick the ground where they were standing like it just gave way. You're not here to impress anyone. Quit making excuses and get off the tee box. Heck, I don't even care if I'm playing with straight-up cheaters, or people who are incapable of even connecting with 2/10 shots... But something about someone thinking that I care how they do bothers me.
I guess I treat golf as a personal game. I don't play to win or lose, I play to do better than I did last week.
