Dining Etiquette - UPDATED

I've been at several dining events in the last year with people I assumed should know the proper placement of dishes on the table. In a group where I'm the youngest, why am I the only one who knew? Anyway, here's an easy way to remember it: BMW (bread, meal, water). Your bread plate is on the left and your glasses on the right. Left to right...bread, meal, water.

Update: One more thing...
When you are finished eating, your utensils should be placed diagonally on the plate, side by side, with the handles at four o'clock. The knife blade should face the center of the plate.
