Rule #7: Sit up straight


Cavemen went extinct thousands of years ago, with the exception of the highly evolved Geiko Cavemen. But even the Geiko Cavemen know how to behave themselves in a fine dining situation.

Rather than hunching over your food and shoveling heaps into your mouth, sit up straight, keep your elbows close to your sides, and lean forward over the plate. You'll look put together, well controlled, and not seem like you haven't eaten in ages.
