1. When helping a woman pull her chair to the table, hold it and guide it. Don’t shove it against the back of her legs.
2. If you’re seated at a table with eight or fewer guests, wait for everyone to be served and for the hostess to begin eating before you dig in. At a long banquet table, it’s OK to start when several people are seated and served.
3. All things not having to do with food should remain off the table: keys, clutch bags, cigarette packs, sunglasses, BlackBerrys.
4. Don’t snap your napkin open or unfurl it showily like it’s an Olympic flag.
5. If you prefer not to have wine while dining out, don’t turn your glass upside down, and don’t make a big deal of saying you don’t drink. Simply place your fingertips on the rim of the glass and say “Not today, thanks.”
