It's not proper etiquette to argue over the bill. Avoid this problem by arranging in advance that the bill not be brought to the table. Check the bill to see if a tip has been included. The tip is typically 15 to 20 percent of the total bill. Other service personnel should be paid directly.
Most table manners are common sense.
Order the meal before discussing business. Chew with your mouth closed. Swallow your food before speaking. If you want to comb your hair or reapply lipstick, do so only in the restroom. This also applies to using toothpicks or nose blowing.
