I have been to so many networking luncheon meetings and even formal dinner parties where someone at the table picks up the wrong glass and throws the whole table off because they weren't aware of the proper etiquette. There is a very simple solution to figuring out which glass and which bread plate belong to you at the table setting.

With your left hand, form a circle with your thumb and pointer finger. The other fingers stand straight up behind the circle. This makes a lower case b. Do the same thing with your right hand, which makes a lower case d. When you do this at the table, you will see that your left hand (lower case b) is where your bread plate sits. B for bread. Your right hand (lower case d) is where your drinking glasses are. D for drink.

You can do this surreptitiously under the table cloth if that makes you feel better, but you will never again pick up the wrong water glass, bread knife, etc., if you just follow this simple tip.
