The Buzzing Door

I work in a psychiatric prison hospital.  Getting into the facility involves passing through 4 locked doors and 2 locked gates.  An electric "buzz" signals that it is possible to open the portal... Sometimes, as I go through the building, I stand waiting at an unsecured door, as if it too has to be buzzed open.

It is really embarrassing in a free world facility to stand and wait for the "buzz" that would allow me access.  But it happens to me frequently...Does that tell you what a creature of habit I am?
