Greeting: Replying to greeting while eating

Q241 :It is suggested that replying to a greeting while eating is discouraged. Is this true?

A241 : This is simply a wrong interpretation of a social tradition which suggests "no greeting during eating". What this social tradition means is that a person who passed by another or a group who is eating need not greet them. He may join them without even saying hello. This should not be interpreted literally. It simply means that a passer by is welcome to share the meal. If someone greets you when you are eating, you must return his greeting, because this is a duty in all circumstances.
