Sign

We have a sign at work that stops you leaving through an automated door and forces you through a turnstile type door instead. Neither door has security on it, but the automated one gets people through quicker. Why it's blocked is beyond me.

The sign states that the door is for disabled use only. They then stick the sign right in the path of the opening door. So it won't open. Utter genius.

Hopefully the pictures come out clearly enough.
