What are the principles of napkin handling?

Place your napkin on your lap when you take your seat, or wait for your drink to arrive. “If you wait for the food to arrive, the server will have no place to set your plate,” says Robert Burke, a waiter at Chez Panisse, in Berkeley, California. If you leave the table during the meal, loosely fold your napkin and place it on the table to the left of your fork. While some authorities recommend putting the napkin out of sight on the chair, Nathalie Dupree, a cookbook author and the host of the PBS series Nathalie Dupree’s Comfortable Entertaining, says, “Napkins are meant to get messy; there’s no need to hide them.” Besides, the napkin could soil the chair, which could then soil your clothing. At the end of the meal, too, set your napkin on the table.
