Sorry, I don't keep up on fast food news. I just read about this and got a laugh.
It reminded me of when I was a teen and worked at a sub shop next to a KFC - a KFC I decided was afraid of vampires, because they closed really early - before 8pm on Fridays and Saturdays (we were open until 11pm those days and left at midnight).
But they left all their lights on, including the drive-through. And we would laugh our asses off watching cars line up at the sign, honking their horns, driving up and tapping on the window. If there was something going on locally, you'd see cars lined up around the building. We would even take bets on how long it'd take people to figure out they were closed.
