@SEzra31589 Big difference. Just for starters: A nun is a member of a very specific religious community with specific rules and restriction. She has chosen to do so out of her own free will. It looks the same to a certain degree but it is totally different.
@miracles7k As a vegetarian, the question would not be asked to me. Assuming it is not an islam country `(if it were, there would not be bacon on the menu) my answer would be โnoโ, in a polite way. Religion and public space should not be mixed. Be religious in your home, not in public space.
