In less than two months, holiday entertaining will begin for some. And that means hors d'oeuvre platters. So, here's an etiquette tip... Never eat over platters and serving dishes. When eating over a platter, you will spend more time than necessary in front of it, blocking others from getting to it and quite possibly holding up a long line. Plus, no one wants to see (or imagine) your crumbs or bodily fluids falling onto a platter. So please be considerate and keep the cheese platter clean and free from obstruction.
