2. Cultural Ignorance and Narrow-mindedness.
This is one of the most important points and it should definitely be taken into consideration. Before you set out, find out about the country you are going to. What is normal for you might look absolutely inappropriate elsewhere. In the United States there is no need to take you shoes off when visiting your friend’s house. In China or Japan entering someone’s home with shoes on is impolite. Be open-minded and never judge the food before you try it. The only excuse for not eating exotic dishes would be allergy from some certain ingredients.
