Forks on the left, spoons on the right

Dad has a bad habit of keeping the serving spoon or fork when he fixes his plate of food.  When I go to dip my serving, there's no utensil with the dish because he's got it on his plate.  I pointed this out to him yet again the other day.  He told me he was sure there are worse sins in the world.  I thought a minute and informed him that he was probably guilty of those as well.
