Unfolded if it’s a lunch napkin and folded in half if it’s a dinner napkin! My table manners with cutlery aren’t the greatest. I think I take too big bites of food. If I’m at like Costco food court or something I do put my elbows on the table. I would rather be shot dead in the street than ever speak with my mouth full obviously. I put my phone away when I’m with someone and generally when I’m in public. My posture is always excellent. I avoid profanity in public. I’m definitely more relaxed overall in private. I believe if you’re on time you’re late, so I’m always punctual. I also follow basic etiquette rules of behavior like being helpful and friendly and interested in what other people have to say, putting them at ease, making eye contact when speaking, etc.
