I imagine pulling one of those blinds open and seeing that background of endless skyscrapers around your own, with no activity anywhere. Except when you briefly spy "something" in a far window, that suddenly turns and looks at you then runs out of sight. That was one of the most frightening scenes in all the Backrooms stuff.
No joke. My guess is the "fake" stores at the abercrombie HQ, or one of their testing offices. I recognize the door and how there's an interior wall behind the exterior wall.
Probably wrong, but it brought back memories of a crappy summer in highschool
