I wasn't there so I cannot comment on what went down between the old geezer and the young "league" woman, but let me ask a question about giving "unwanted" help to someone: If you see someone, possibly a beginner or fairly new player, practicing at a table near you and doing something (making a bridge, stroking, etc.) that is ABSOLUTELY wrong, would you rather see this person continue to pound this bad technique into their muscle memory/thought processes, or would you rather take a chance and ask this person if you could show them a couple of things that would improve their practice sessions/overall game???
I can tell you that I am the type of guy that would ask this person if they wanted a few "tips". I do it on occasion and WAY more times than not I am allowed to help them. Get thanked afterwards too! Spent anywhere from a few minutes to HOURS working with "newbies", by simply asking them if they wanted some pointers.
IMO, it is a foolish person, man or woman, that is a beginner to a game in which they wish to do better in, that refuses to at least hear what someone has to say to help them. That said, I do realize that there are some "self-appointed" instructors that give out bad instruction from time-to-time, but the newbie could later defer to someone "in the know" to determine if this was good info or not that was given to them.
My point is, I don't think asking someone if they would like some pointers is out of line. The person being asked can always politely decline. I personally know some players (one lady on my 9-ball team) that wants to shoot good pool, but doesn't want to hear a damn thing from any of her upper skill-leveled teammates. I say let her wallow around in the bottom of the barrell if that's gonna be her attitude.
Just sayin'.
