Janitor Impersonation Infiltration

Arthax: That was... Demeaning.
Yeagar: I never knew you could storm a castle like this...
Nodwick: The thieves' guild would be unstoppable if they invested in blue coveralls with the name "Al" embroidered on them.

Okay, so you have to break into this high tech science lab, or a government facility, or a fancy bank, or something. It doesn't really matter what this place is to you, because it's swarming with security and there's no way you'll ever get in...or is there?

Enter the Janitor Impersonation Infiltration. Custodians, janitors, cleaning ladies, what do these people have in common? They have access to every room in the building and might as well be part of the scenery. No one pays attention to them or wonders what they are doing sneaking around after hours while everyone else in the building is gone. So if you are looking for an easy-in, they are perfect candidates for impersonating when one has to steal that secret formula or those hidden financial records.

Other similar jobs which have the same relative anonymity of the janitor and are Beneath Notice may also qualify for this trope. Being that these people might be secret agents, there's a definite possibility of Almighty Janitor overlap. Compare Dressing as the Enemy, The Infiltration, Room Disservice and Delivery Guy Infiltration. Depending on what is done with the real janitor, may overlap with Mugged for Disguise, and you might want to be careful about running afoul of Because I'm Jonesy. If the impersonator seems to do this often in different situations, it might be a case of New Job as the Plot Demands. May overlap with Black-Tie Infiltration if infiltrating a party as the hired help.
