First off, some people are jerks on the course, no getting around that. Just make up an excuse to start over or drop back a group to get rid of them. Second, when you come across these guys, just ignore them as best as you can and play your own game. Unless you are playing some sort of game for money or stakes, just do whatever you want. As a beginner, you don't have to play by the strictest of rules and you don't need to keep score. It is commendable that you want to, but if you sense things are going bad on the day, just forget about them and play to try and improve. Don't ever let someone tell you to walk back to the tee (unless of course something is at stake). Just tell them you'll drop here and play on. You are doing your thing, they are doing their thing, just leave it at that. Golf is supposed to be fun. If it isn't, you are doing something wrong, regardless of the playing partners. I have played with all types, you just have to learn to tune them out and do your own thing. Some are better than others, sometimes you just have to be a duck.
