The Initial Placement
Upon being seated at a formal or semi-formal American dining table, you will typically find the napkin placed to the left of the forks. It may be folded in a simple rectangle, a triangle, or a more elaborate fold. In some settings, especially at more casual restaurants, the napkin might be placed on the center of the dinner plate. The key is to wait for the host or hostess to pick up their napkin before you unfold your own, as this officially marks the beginning of the meal.
During the Meal
Once the host has given the cue, carefully unfold your napkin and place it on your lap. The napkin should remain on your lap for the duration of the meal. It is used for dabbing the corners of your mouth discreetly. If you need to leave the table temporarily during the meal, the proper etiquette is to loosely fold the napkin and place it on your chair or to the left of your plate. This signals to the staff that you intend to return. The napkin should never be placed on the table until the meal is completely finished.
Concluding the Meal
When the meal is over and you are ready to leave the table, the host will typically signal the end by placing their napkin on the table. You should then follow suit. Place your napkin neatly to the right of your plate. It should not be refolded tightly, as this might imply it is to be reused, but rather gathered loosely. Avoid crumpling the napkin or leaving it on your chair at the end of the meal.
By following these simple guidelines for napkin placement, you can navigate American dining situations with confidence and grace.
