Where am I?

I had previously been visiting Starbucks cafes only in the US (because for a long time there were not any of them in Finland). Once I went to a Starbucks in Finland. I was looking at the menu boards and the names of the drinks which were in English.  I was in my thoughts, selecting what would I want to drink. Then it was my turn to be served. Suddenly I did not know in what country I was, what language should I use.
