My ENTIRE building (30 floors) just got completely evacuated in a 'fire emergency'.

The reason: Someone pressed the red alarm button that says FIRE on it (with glass over it), instead of the door release button (conveniently placed next to it).

It took about an hour to get everyone out and back in again.
That might just be the biggest waste of time in the history of ever.
Apart from me making this thread, possibly.
My tea's gone cold now...
