When I used to run something big, a army-style thing, but not quite what you'd think... Hard to explain...

Anyways, I would VERY bluntly state in the description, in my opener, even in a drawing, show that there weren't 'hallways'. It was a base, built on an island. But instead of being one massive building that has sections inside, it has multiple buildings on the island with pathways OUTSIDE leading to each building. This was done to make sure people had a high chance of success if they needed to escape because it's much harder to block off 50+ doors than just 10 or so when in an attack.

People, no matter what, would still talk about walking hallways inside a building...and I would be like; "...Did you miss the five times in the description of the RP, base, and my post that there aren't hallways?"

Obviously, I said it nicer than that. Most would edit their posts, only a few bitched. It takes a few minutes of reading. If you're unwilling to read, don't join--period.
