I live here and have a bunch of friends who were either taught indonesian or Japanese at least for a couple of classes in school.
It makes sense, as most of our trade is within the Asian region.
I know this may come as a shock to those in the US, but learning a language other than English is pretty common in other English speaking countries, especially in the Eurozone.
Most of the people working in hospitality I dealt with during a 6 week tour of Europe (inc, France, Germany, Italy, Switzerland, Czech Republic, Hungary, etc.) spoke at least 2-3 languages. One of our swiss tour guides spoke at least 5.
Knowing the native language of those you work with or trade with is useful. You may be very surprised at what may be getting said between others right out in front of you if you don't understand, or the other guys think you don't understand.
