I think it's entirely that.
Film and TV is full of little things we never notice, TV Tropes does a good job of cataloging them.
A well known one is the taxi scene. A character gets out of a cab, hands the driver something, the driver waves/tips their hat (in a period piece) and then drives off.
Has anyone really, ever, settled a cab fare that fast? There's small talk, digging around in pockets. sorting out a tip (or not, which is it's own story) and then change.
But when your protagonist has to get into the building, you're not going to go through all of that.
It's too easy to regard these conceits as faults, whereas they're really just shortcuts to the things that matter.
