And pretending to be a warden, yes.  But it’s not like there’s any oversight on that?

[Probably because it isn’t sustainable.  Not without becoming incredibly obvious, sooner or later. Still, he does take a look at the ID card she presents to him - while he still has his doubts he has to admit that it at least looks plausible as a warden item.]

And honestly, I'm almost surprised more people don't try it?

[Or maybe just don't think to try it, although that works out to about the same thing in the end.]
