DON'T leave the table during dinner. It's considered rude.
DO keep your hands above the table, even when you are finished eating.
DO place your fork and knife on the right side of the plate to indicate to your server that you are done eating.
DO insist repeatedly that you don't want more food once you are full. Otherwise, you will be offered more.
DO keep your wine glass relatively full if you do not wish to drink anymore, otherwise your glasses will be topped off if it looks only half full. Do not refuse when you are offered a top off.
DON'T eat with your fingers. Use a fork and knife, even for food that you may normally eat with your hands, such as a piece of bread.
