This is probably less about style, and more about simple presentation and manners when one is in public. WHY ARE SOME PEOPLE SO DAMN LOUD? (yes, all caps on purpose). I have never been able to fathom why some people find it necessary in a public place (in a restuarant, on an airplane, in the restroom, etc) to talk so loudly. Do you want people to hear every tidbit of your conversation? Do you not realize how much your voice is carrying to every nook and cranny of the room/space you're in (and expecially into the ear canal of the person lucky enough to be seated next to you)?
