There is nothing that boils my blood more than dress codes. Sure, don't show up somewhere naked, but other than that I really don't care what people wear. Of course, it goes without saying that these clothing rules mostly apply to women and children, because sending a kid home for the width of their spaghetti strap is far more important than that young girl learning, right?
If you think that's annoying, just wait to see what happened to one woman while she was out running errands recently.
