Rule #1 for Eating Soup
When eating a spoonful of soup make sure that the soup is taken away from the outside of the bowl or plate-away, not toward you- so that should a drop of soup should fall it would land in the bowl, therefore not on you.
Rule #2 for Eating Soup
There are different rules for eating clear or soups with "objects" in them like meat and vegetables. When eating clear soups at a business lunch, the soup should be eaten from the side of the spoon. For soups with "objects' in them a person should eat them from the front of the spoon.
Rule #3 for Eating Soup
There are varying opinions about drinking from a soup bowl, but when it comes to business lunches and drinking out of a bowl, it is something an individual may never want to attempt. But if chooses to do so, here is some advice, if the bowl has handles and the soup is clear then you may drink. When drinking from a soup bowl make sure to tip the bowl away instead of toward you.
Rule #4 for Eating Soup
Where to place the soup spoon at a business lunch is an important bit of information to know. Between sips, the spoon can be placed in a plate or in the bowl. When completely finished eating, the spoon should be placed on the saucer's left side, beside the bowl or the lower right hand side. If the soup is served in a shallow soup plate or dish leave the spoon in the soup plate when you have finished.
So as not to inconvenience the wait staff it is best to place the soup spoon on the right side for easy removal. If the soup is served in a narrow soup cup, place the spoon on the saucer between spoonfuls to avoid having the spoon standing straight up in the cup.
