On an upper floor, there's usually still a back door but the hallway may dump you back out near an elevator or escalator. I note the "back door" of whatever store I'm in if it's unfamiliar to me. It's not always obvious, particularly in a clothing store.
Bars are trickier, I'm sure. Especially a multi-level affair, like some of them downtown here. If you're on the 3rd floor and don't know where to access a fire escape, are drunk, and panicked, good luck.
