When I was in grad school, one of the other grad students lived in his office. We all looked the other way when he shifted the desks around (leaving a couple of the other grad student desks kind of cramped) to make room for a sofa. "Yeah, that'll be real comfortable to... sit on... while doing math. That's what it's for!"

I'm pretty sure all of the faculty and staff in our department knew about it too.

I think there's a difference between doing this in your office, and an office you share with others.

If I needed to stay late to study, or grade assignments, or whatnot, I would be pretty annoyed if my office-mate asked me to leave because it was his bed-time.

I think "throwing people working late out" isn't one of the things you get away with doing that.
