He was working for the cleaning business, though. If the company was letting in anyone who works for that cleaner without further investigation, that's their problem. That's the situation we were talking about upthread, so I assumed
zcrackerz would have said something if it were different.
Where I work, each cleaner gets a badge, just like the engineers. Presumably she gave her badge to a random other person, aka her boyfriend, so he could let himself in. Nothing stops me from doing that as an engineer either, but it would absolutely be a firing offence if caught.
