Teenagers at a fancy restaurant?

Act like you're eating with important people, and not like a bunch of animals. Don't shovel your food into your mouths, speak politely and you shouldn't have any problems. We couldn't take my Step-Son out to eat at any nice restaurants. Everybody would think he was raised by savages in the wild the way he would eat and carry himself. His GF left him because he was so embarrassing to be be around too.
