Speaking with your mouth full is without question the antithesis of manners. But what many don't realize is that there’s plenty you can say at a meal without speaking a word. Instead, dashing diners let their utensils do the talking.
Though a place setting may have several different utensils (salad forks, fish forks, soup spoons, etc.) the dinner fork and knife are the only two required to communicate wordlessly with the wait staff.
