I had a similar experience while in Japan. Perfect time to use the Google Now currency card, right?
Nope, as soon as I set foot in Japan, the currency card doesn't show up in Google Now. The world is only going to become more and more internationally linked; hopefully Google figures out a better way to manage this than they have so far.
It seems Google has never been able to figure out that people actually travel between countries, which is amazing given how much the Googlers I know move around.
Great example is translations... often various Google properties speak the whatever local language to me, even though I'm logged in. While it has been a while since I've seen GMail in Turkish, this still happens frequently with search.
Two issues here:
1. my Google account knows what language I want to use
2. language !== country. Many countries have multiple official languages, not to mention immigrants etc.
