Dear Queenie,
Whenever I see or smell someone eating a cough drop I think how rude it is to do that in public.
Queenie, maybe if you tell them they will pay attention!—Annoyed
Dear Annoyed,
Eating a cough drop in public in itself is not rude. Some people have allergies that make them cough.
However, it is more than rude to go out in public if one is sick, especially these days. Even if what the person has is not COVID-19, they should stay at home with it.
