A MARTÍNEZ, HOST:
Good morning, I'm A Martínez. New York's Metropolitan Transportation Authority has a new message for riders - be nice. With more workers heading back into the office these days, it seems that many have forgotten some of the rules of riding mass transit. That's why the MTA's Courtesy Counts digital advertising campaign is politely reminding riders, among other things, to keep phone calls short, keep your feet off the seats and please save your personal grooming for somewhere else. It's MORNING EDITION. Transcript provided by NPR, Copyright NPR.
