I've stumbled upon this article before thanks to a tweet by @azforeman (https://twitter.com/azforeman/status/1370779212697628672), which I'll reproduce here:
> I once was sitting in O’Hare airport reading a book of Latin poetry when a guy looking like a monk walks up to me looking utterly lost and asks “Loquerisne Latine”? (Do you speak Latin?) To which I answer “Ita, possumne te adiuvare?” (Yes, can I help you?.)
> Turned out he was indeed a Polish monk and knew only Polish and Latin. Had never been outside Poland before, or even seen the inside of an airport, and needed help finding his way.
> That is my personal story of Latin as an auxlang.
