It's annoying to make a squeaking noise while eating. Some people make noises when eating, which will affect other people's moods and make people impatient. Especially in public, people who can't stand making noises when eating are worried. Because they don't know each other, they are embarrassed to say it in person, but they feel uncomfortable when they don't say it. Therefore, it is necessary to discuss whether eating can make noises in public.

Some people have long been used to making noises when eating, thinking that this is a normal phenomenon of eating and never thinking about the way of eating. Therefore, why some people make a squeaky sound when eating is also a cognitive problem. Due to the limited cognition, I didn't realize that it is impolite to make a beep when eating.
