Yeah, good point. No key like a car.

Based on multiple places I've worked, the stereotypes surrounding cleaning crews frequently ring true: seemingly recruited off a pizza-box ad and more interested in stealing stuff than in cleaning.

Could I imagine one of these types breaking into a closed airport bar and stealing alcohol? Perhaps. But making it into an airplane via an emergency exit or even the main door?

On the other hand, if this were a crew hired to clean the actual airplane, I could easily imaging someone prying open a cabinet that has alcohol in it...
