Which of the following is NOT considered a table manner?

The choice that is NOT considered a table manner is talking with food in your mouth. This behavior is generally viewed as impolite and can be unhygienic, as it is not only difficult to understand someone who is speaking while eating, but it can also create an unpleasant dining experience for others. Good table manners emphasize respectful and considerate behavior at the dining table, which includes clear communication, but not while food is in one's mouth.

In contrast, using appropriate utensils, refraining from placing elbows on the table, and not slouching while eating are all recognized as essential practices of etiquette that contribute to a pleasant dining atmosphere and demonstrate respect for fellow diners.
