When I watch American dramas. People in the United States use fork and knife tools when eating. Koreans sometimes eat food with their hands, but it seems not clean This is very important etiquette. Using tools without eating with your hands It looks so clean What's more surprising is that in Korea, if there is a food you want to eat, you reach out and take it. This makes the person next to you uncomfortable. But in the U.S., they ask you to hand them what you want to eat. I really envy the U.S.
