Good thread. Like others, I succumb to the realities of public course play and rarely do the walk of shame back to the tee because my ball is lost somewhere in a mountain of leaves. Otherwise, I play it pretty straight and dread the times I have to make a judgement call (like when a pond that is ALWAYS staked red is suddenly missing it's stakes!).
I have a close friend who is an Englishman, and he is hard-core on the rules. He has made me re-tee a couple of times because my tee was an inch in front of the tees (you know how on public golf courses the tees often end up cockeyed by the end of the day). He is a pleasure to play with, and I always learn something new about the rules that I didn't know before. I generally play match play with him so I can easily concede a hole or a short putt to him in order to keep pace. He's always shocked when I give him a breaking two footer to halve the hole, but I'm always VERY aware of the group behind me and, if they are waiting, I generally concede the short ones. If we played stroke play we would have a hard time keeping up, but match play it works perfectly and is a lot of fun!
