TABLE ETIQUETTE #2
Accidents, or anything that may be amiss at the table, should be unobserved by a guest unless he is the cause of it. In that event, some pleasant remark as to his awkwardness should be made and no more. The waiter should attend to the matter at once. If a ford or a spoon is dropped, it should not be picked up by the guest, but another used; the waiter should be asked to provide one.
