I live in Washington, DC and between diplomats, armed forces/intel agency members, and tourists you can never tell who can understand what language.
This was a while back before smartphones. A small group of tourists were speaking among themselves trying to figure out how to get to a tourist site. A older, well-dressed African gentleman went up to them and helped them in their native language. I was waiting at the crosswalk next to him afterwards and asked what language they were speaking, he told me it was Russian and he was a diplomat from Nigeria and knew Russian from earlier in his career.
