In the case where the person on the other end isn't a native english speaker, (the calling a restaurant clip) why doesn't Google figure out what language they speak and speak it to them?
Many consider Scots to be an actual language separate from English. There's a good amount of debate about this among linguists, I think.
For anyone curious, I recommend reading these pages from the recent Scots translation of the first Harry Potter book to get a feel for how it differs from English.
oops!
