Do you consider it rude if you go out to eat, and someone isnt hungry and doesn’t eat anything? In the case of dining out, is it a faux pais in your culture if one of the guests doesn’t order food?
For simplicity, lets say they aren’t eating because they are full. So pickiness or passive agression isnt a factor. Rude?
Personally I dont consider it rude. If they are with me and not hungry, then they still enjoy my company and conversation. If they didnt want to see me eat they’d decline, also acceptible in my book.
