Turkey, India and Saudi Arabia are the only countries where burping after eating is considered a compliment. Other countries have different traditions, like slurping and passing gas, to indicate appreciation of a meal.
Though these things are the norm in other countries, they are generally considered bad manners in American culture. There are a number of mealtime traditions from around the world that those from other cultures often consider odd. For instance, in China it is considered bad luck to flip a fish while cooking, and in South India etiquette dictates that the left hand should never touch a plate.
