Etiquette, which is sometimes unwritten, is a code that governs the expectations of social behavior of people. It usually reflects the cultures and traditions of countries.

With over 200 ethnic groups represented the people of the Congo have a wide variety of customs, traditions, and values. They vary from place to place and group to group, especially when it comes to living in urban areas and rural areas. Therefore the etiquette rules differs depending on where a person lives.

Greetings consists of speaking, shaking their hands, and smiling. In the rural areas, men and women do not shake hands. Men will shake the hands of other men. Some women will greet men by clapping their hands and bowing slightly.

Men and women use separate communal bowls; often, women may sit together. When eating out of a communal bowl, people eat from the space directly in front of them. When utensils are used, the left hand holds the fork and the right hand holds the knife.
Dressing in the Congo is greatly influenced by the Western world, however, they are mixed with traditional clothing such as kikwembe, abacos, or a dashiki. The nicer a person look, the more respect he or she will receive. Jewelry is often made from wood, ivory bones, or shells. Many people in rural areas walk barefoot, but sandals and slippers are commonly worn.
