My friends and I were dining in a restaurant where the waiter placed the napkin on our laps. My friends think that it should be left the way the waiter placed it, which was half folded. However, I think that one should re-arrange it to lie flat and fully open covering one's lap to catch any food that drops. What do you think?
If it was a large napkin, then it should be left folded in half. A small luncheon napkin can be fully opened.
If eating properly, food should not be dropping onto one's lap. Napkins are really meant to dab crumbs or food from the mouth.
