Dining Etiquette
Over breakfast, lunch, and supper, Americans socialize and conduct business. Socializing is limited at the beginning and conclusion if business is the main objective. It's more important to eat during social gatherings than to speak and linger over the food for hours. You should pay if you invite someone to a restaurant.
The knife is held in the right hand, while the fork is held in the left hand with the palm down. If offered, napkins are set down on the lap. A toast may be spoken at the beginning of a formal meal or in honor of a noteworthy guest or occasion. You are permitted to decline specific foods or beverages without giving a reason.
A lot of food is consumed by hand. Food is frequently served family-style, which entails passing large serving dishes around the table so that each person can help themselves. Wait until the hostess starts or says to start eating before you start. Until you are requested to sit down, keep standing. Avoid leaning your elbows against the table.
