Learn a little bit of the language of the country you're traveling to. You can find the basic phrases online or in a travel guide. Even if you're terrible at the language, it will win you brownie points with the locals you're communicating with and even might help you get out of a sticky situation. Locals will know you're a tourist, but they'll appreciate you trying to speak their language. Ja, natürlich!
