RE: Simple bowling etiquette that everyone needs to know

not being aware of something isn't really rude though is it? You didn't know so there is no foul here. The same can be said for most of the people that I encounter here that break the rules. They are unaware they exist. Since I don't speak Vietnamese I will kind of let my neighbors know that I am displeased with them invading my space by simply stepping back and waiting for them if they invade my space. I've noticed that this tactic takes a while, but they get the hint without anyone getting angry.
