Table manners vary from place to place. I have always been told that the custom of cutting all your food up and then eating it with your fork held in your right hand is American, acceptable there, but not in Europe.
In Denmark we tilt our soup plates towards ourselves in order to get the last mouthful onto our spoon. As a child in Scotland I had to remember that there you tilt your soup plate away from yourself, but a dessert plate towards yourself.
In Denmark you may rest your hands on the tablecloth, but I remember being told that in Britain they must stay on your lap, if you are not using them to eat.
Here you may pick the meat off poultry using your fingers to hold the bone, in France this would be the height of bad table manners.
In Scotland you butter a piece of bread, add jam then eat it. Some of the girls at school who came from the south of England had been taught to put a knob of butter and a spoonful of jam on the side of their plate, and butter the bread and add jam a mouthful at a time.
