The one I know has several signs on the exposed inside walls above the topmost floor all assuring you that you will not be turned upside down, or folded, or run through a meat grinder.

Based on the adage that every (non-)warning sign is there for a reason, I can only assume that there have been incidents of people panicking after they realized they had gone to far.

Just to be clear: it’s absolutely safe to go around. Any other stories you may hear are the inside joke of those five beaurocrats on the top floor enjoying their tiny fiefdom of chaos.

Edit: could people downvoting this please give a reason? I’m really not complaining, just terribly curious what could possibly stroke people the wrong way in this benign post. Or is this the Paternoster conspiracy coordinating to keep their secret?

There is a variation which isn't - the "man lift".[1] Those are dangerous, and sometimes seen in parking garages for staff only. Those really do turn upside down at the top. They're usually equipped with a switch to shut them down if someone rides past the top landing.

Sometimes they try to scare people because there are actually "hidden" rooms (for technical stuff) and they don't want them messing around there.
