I played with a guy on Saturday - young guy. He was meticulous about not walking in our lines, but went around fixing ball marks while everyone else was putting. I realized after a few holes that he was probably fairly new to golf and didn't quite have the etiquette down. On the 17th hole, he wandered into the 18th fairway searching for his errant tee shot. After he finally found it, he hit it about 10 feet, then hit it again. Did I mention his set-up took forever. Anyway, the people on the 18th tee were livid by the time he finally got out of the way. So I said something to him when we walked off the 17th green. Turns out he didn't know about yielding the fairway. Normally, I wouldn't have bothered, but he did seem like he wanted to learn. Do you speak up when someone is making an etiquette faux pas?
