In North AmericaA table cloth extending 10–15 inches past the edge of the table should be used for formal dinners, while placemats may be used for breakfast, luncheon, and informal suppers.Modern etiquette provides the smallest numbers and types of utensils necessary for dining. Only utensils which are to be used for the planned meal should be set. Even if needed, hosts should not have more than three utensils on either side of the plate before a meal. If extra utensils are needed, they may be brought to the table along with later courses.Candlesticks, even if not lit, should not be on the table while dining during daylight hours.Men's and unisex hats should never be worn at the table. Ladies' hats may be worn during the day if visiting others.Do not talk on your phone or "text" at the table, or otherwise do something distracting, such as read or listen to a personal music player. Unless you are alone, reading at the table is permitted only at breakfast.If an urgent matter arises, apologize, excuse yourself, and step away from the table so your conversation does not disturb the others.If food must be removed from the mouth for some reason, it should be done using the same method which was used to bring the food to the mouth, i.e. by hand, by fork, etc., with the exception of fish bones, which are removed from the mouth between the fingers.The fork may be used either in the "American" style (use the fork in your left hand while cutting; switch to right hand to pick up and eat a piece; this is common practice in the US) or the European "Continental" style (fork always in left hand). (See Fork etiquette)Do not leave the napkin on the seat of your chair, even if leaving temporarily. A dirty napkin is not to be placed on a chair seat, which may mark the upholstery. Similarly, one does not again use a napkin that has been on the seat of a chair where one has sat. When you leave the table at the end of the meal, loosely place the used napkin on the table to the left of your plate.
