Macau sets Portuguese as one of its official languages, but according to the Wikipedia page, only 0.6% speak it at home.
However, people speaking it at home should be those who use it as their native language, right? So I might guess that there are slightly more people speaking it as 2nd or later languages.
If you speak Portuguese, is it useful in Macau today? Or what kind of people or places or districts can you use your Portuguese? Are people speaking it Chinese descendants, or Westerners-looking? And finally, is talking to people in Portuguese possibly an insult here?
