One aspect of the episode which seemed kind of funny for about two seconds until I got the point was taking a camera phone picture of the emergency evac sign next to the elevator, and also how Cade's "rear security" guy had to keep sticking those Post-it's along their route.

I think the average viewer may think those two actions are odd and ridiculous. But the average person doesn't realize how disoriented you can be in a fire--dim lightning, blinding smoke, stress, unfamiliar office layout on a different floor, etc. Unfortunately, thick black smoke makes for boring TV images so I don't think that they really got that point across in the show. They did show a lot of flames, though. Most people still probably think that "a fire" looks like a lot of flames when in reality there's a good chance you won't see any flames because you can't even see your hand in front of your face from all the smoke.

They never did have to backtrack and use those Post-it's, did they? I think that would have been an interesting thing to demonstrate and then people would understand why they did it.

Would first responders be trained to follow that Post-it trail? Personally, I think the bread crumbs were just for them, but maybe it's like someone stranded in the bush putting down an arrow showing their direction of travel? Or maybe to help them realize if they ever went in a circle.
