Traveling abroad is an incredible experience. However, oftentimes, tourists don't do enough research about the customs and norms of the country they're visiting, and they end up accidentally inconveniencing locals or embarrassing themselves.
For example, when you're shopping in France, you should greet the proprietor to be polite.
And when you're in Japan, you should take off your shoes before entering somewhere like a private home.
And in the US, when you're at a restaurant, you're expected to leave an approximately 20% tip for your server.
