There's a group of European travelers scanning a subway map. Realizing they have no idea what they're doing they stop a guy in a business suit and ask in a thick accent -
"How do we get to Kennedy airport?"
The guy obviously recognized their accent and broke out into their language. They had a quick conversation in a tongue I didn't understand.
Toward the end of the conversation I caught one word in English - "Taxi" as he pointed to the staircase leading out and handed them a few $20s as he said his goodbye, obviously intending that they not spend their last few hours in NYC in the subway. They happily accepted and booked out of there.
