I usually play with a circle of about 5 different guys, all with handicaps of 12 or lower including a scratch and a 2. None of them are rude or anything but encouraging to me. I will pick up if I ever get to double par, and if I ever birdie or par, they act like I won the Open. They will always point out good shots, and save any instruction for after the round. Behavior like this is inexcusable. Unless your'e on a tour, anybody who sides with this guy needs to re-evaluate their priorities in life. Golf is a game for most of us. A way to relax, get outside, exercise and enjoy being with our friends or family. Some of us don't have the time, the means, or the talent to play as well as we would like to. If you don't like playing with high handicappers, thats fine, but if you get stuck with one, there's no reason to act like a jerk. You can always be civil and accomplish what you want. If slow play is the issue, whats wrong with "Hey man would you mind picking up if you hit double par, so we can keep moving?" That would have accomplished the desired goal and I bet you would not have had a problem with it. If the problem was your scoring, then this should have been taken care of from the outset, and I blame your host for this. If I ever witnessed my son treating someone he just met like this on a golf course or anywhere else, I assure you that he would wish he hadn't!! I applaud your restraint.
