There nothing noteworthy about walking past a locked door. Best to assume most doors you walk past are locked, frankly. And should that door have a card-swipe, no big deal, you see that all the time. Now, a door with a card-swipe and a number pad? That’s a little more unusual, how come you need a multi-factor locking mechanism. And if that electronic lock has an armored camera pointed at it? Then maybe, maybe you take notice. What I want to know is, do you finally start asking questions when someone drops off the copy of Introduction to Nuclear Engineering that they borrowed?
