Three Cups of Tea question

My book is about a man that travels to South East Asain and African countries to build schools and better the living conditions of the areas. Have you ever gone to a new country, place, or area and not known the customs or public norms of the culture there? Have you ever been uncomfortable in a place you have never been? If so, explain why and how you reacted. If not, say how you might feel if you were in such a situation.
