This sums up my experience travelling and living abroad. To your point on vocab choice: if I use vocab not present/with different meaning in American English I would get blank stares so I often switch to the American term e.g. mobile phone vs cell phone. To your other point about local slang: I recently learned South Africans call traffic lights "robots", which I thought was fantastic.
