One of the essential points of learning how to wear a nice suit is learning how to not get it grubby when you're eating, whether you're eating spaghetti or crab or a ham sandwich. I say the guys wearing the napkins are just losers who never learned how to dress right.
The alternative, of course, is to wear jeans and a t-shirt, because if you get tomato sauce on your jeans, it's ok.
