One exit was confirmed to be blocked by a soda machine, but I doubt that accounts for most of it. There were a lot of people there, and many got out, so people DID exit... but some were going to be in the wrong place, and others probably fell victim to the fact that the average Joe is not aware of their surroundings on a good day, let alone at 2-5am while possibly a little buzzed. The fact that so many seem to have hidden and crowded into a bathroom is proof of that to me, but I see it daily.
My boss has worked at the same building with me for 3 years or so now, and when I was talking to her I mentioned something about going down the back stairs. This is a very small office building (two dozen people total, so not some sprawling thing), but she blinked at me and had no idea we had a back exit at all.
I'm aware of the obvious exits and the less obvious ones, particularly if there are a lot of people around. I'd wager most people on this site do that, too, whether deliberately or instinctively. A good portion of people hiding in a single bathroom with only one entrance/exit is the opposite of that instinct.
