Heads of staff unlocking doors.

[Lady Birb]

Hahaha, good one! If the clown isn't unlocking every door and locker on the station with the all access Minister of Hahatown card I gave him because I thought it'd be funny, then the dozen assistants and traitors who found all my floor cards will.

...might work a bit better on 1.

There is nothing stopping a head of staff from relocking all the doors after beating the shit out of whoever unlocked them.
