Good God, that's depressing
I've been to too many sites consisting of nothing but me (usually struggling to find a KVM, for the Windows boxes), a security guard and a lot of servers (and the telcos have some rather large places). Fortunately, it doesn't happen often these days as most things can be done remotely. A tip if you're ever stuck in one of these places and cold: find a rack of HP servers. Nothing blows hot air like a rack of HP servers.
