That was a great idea, and according to some sources, correct! It is believed that one should wait until the host/hostess unfolds his/her napkin. The situation changes when not at a dinner party: in a restaurant, if the napkin is on the plate, the diner should immediately stick the napkin on the lap. As some restaurants start pouring drinks immediately upon being seated, it is a great way to prevent accidental outfit “water-staining.”
At a less formal dining establishment: as soon as ANY food is served would be an appropriate time to put the napkin on the lap. Since the napkin is often placed underneath the fork, it should be placed on top the lap as soon as the fork is lifted.
When getting up from the table, make sure to put the napkin on the left side of the plate (gently folded). As napkins are to be used for the purpose of wiping food away from one’s mouth, they should not be on the chair, where dirty bottoms are often placed.
Finally, one should not tuck napkins into the top of their shirts (resembling a bib). Using proper table manners (elbows off the table, no licking fingers, asking people to pass, chewing with lips closed) will prevent food from winding up down the front of one's shirt. As bibs are typically used for those who cannot feed themselves, it is inappropriate for a person to tie a napkin around their neck solely for the sake of preserving an outfit (unless eating lobster). When in doubt, don’t wear white. Meaning, don’t go to a restaurant that serves tomato sauce-rich foods, wearing light colors that will get stained.
These simple techniques for appropriate napkin use will help children and grownups alike in the present and future. As etiquette is meant to prevent uncomfortable situations by teaching people how to behave in social situations, teaching children these skills at a young age will ensure that they will have the knowledge of how to behave as adults.
Those Brownies were so excited to know an actual time as to when they should put their napkin on their lap and couldn’t wait to go home and teach their grownups. Watch out parents! The word is spreading…
