Good table manners can disappear fast once people get comfortable. This countdown looks at 20 dining habits almost everyone has been guilty of at some point. From chewing with your mouth open, slurping loudly, eating before everyone is served, using your phone at the table, and double-dipping to interrupting conversations, talking with your mouth full, skipping serving utensils, reaching across the table, picking your teeth, licking your fingers, and putting your elbows on the table, these habits can make a meal awkward surprisingly quickly. We will look at why certain behaviors bother people, which rules matter most in formal settings, and how small changes can make you a much better dinner guest. Whether you are eating at home, dining out, or attending a special occasion, this countdown may expose a few habits you did not realize you had. Watch until the end and tell us which table manner annoys you the most.
