单选题Table manners play an important part in making a favorable impression. The following are some western food etiquette rules for your reference. Arrive at least 10 minutes early unless otherwise specified. After you are seated, remove the napkin (餐巾) from your place setting, unfold it, and put it in your lap. Do not shake it open. At some very formal restaurants, the waiter may do this for the diners. Don"t clean the cutlery (餐具) or wipe your face with the napkin. Never use it to wipe your nose! The meal begins when the host or hostess unfolds his or her napkin. This is your signal to do the same. Once the meal is over, you too should place your napkin neatly on the table to the left of your dinner plate. Food is served from the left. Dishes are removed from the right. Pass food from the left to the right. Never turn a wine glass upside down to decline wine. It is more polite to let the wine be poured. Turn off your cell phone or switch it to silent or vibrate (震动) mode before sitting down to eat, and leave it in your pocket or purse. It is impolite to answer a phone during dinner. If you must make or take a call, excuse yourself from the table and step outside of the restaurant. Following the above rules will make you and your friends feel comfortable.
