The concept of good manners varies a lot when we compare different cultures, values and ways of living. However, when we talk about the western part of the world, the differences are not so big. In my opinion, going to a restaurant in Brazil will rarely be an embarrassing situation. But there are some basic and necessary rules of etiquette(礼节)that Brazilians usually respect every day. They are:

●Being on time is polite, but it is not a strict rule in Brazil. Being late for up to 15 minutes probably will not make a Brazilian angry.

●When you go to a restaurant, be careful to greet the people who work at the place, and don’t forget to greet the people who are already waiting for you at the table. It’s not necessary to hug or kiss everybody if they are already seated.

●You can ask somebody about how the food is prepared and also about prices or tips if you are not sure about them.

●Before they start eating, Brazilians usually say “born appetite” to their friend.

●You should never talk to another person while you still have some food in your mouth.

●Making noise while eating is also considered really rude. Avoid doing it.

●Be careful not to put your elbows on the table while eating. It is not terrible, but it can be considered a little bit rude by some people.

●Don't worry about the time. Usually people in Brazil stay seated for a long time, especially when they have interesting things to talk about.

●It’s not necessary to talk in a really low voice because people there usually talk in a little loud voice. But please, don't exaggerate.

●Finally, saying “thank you” and “bye” are always seen in Brazil.
