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.”

6. If you’re eating and want to take a sip, dab your mouth with your napkin to avoid staining the rim of the glass.

7.Grabbing a bowl of salad or a saltshaker as it’s being passed to someone who asked for it is the equivalent of cutting in line: greedy and rude.

8. On the subject of passing: Dishes go counterclockwise, but if someone to your left asks for something, you can hand it directly to him.

9. When you excuse yourself to go to the restroom, just say “Please excuse me.”

10. When out with friends or family — even at a fancy restaurant — it’s OK to ask for your leftovers to be wrapped. But don’t do it at a business lunch or dinner.
