In The Mule (2018), after having lunch at Midwest, Earl suddenly bumps into the Sheriff. He gives him two cans of caramelized corn:
Earl: I went to a charity and I got this caramelized corn. And it is really terrific stuff.
Sheriff: We can't accept this kind of stuff.
Earl: Oh, you'll be doing me a great favor, if you would. I've got diabetes. I can't have it. They'd love it down at the station. And the gals upstairs, they'll love it, too.
What "upstairs" is Earl referring to?
