Friend of a friend story:
Today in the staff room, someone (not naming any names) burnt their toast. The smoke alarm didn't go off audibly in the actual room, but large numbers of people suddenly seemed to be exiting the building. When the culprit tried to inform people that really there was no need as it was only burnt toast, the person in question discovered that it was too late-once the alarm has gone off, a train of events is set in motion that involves evacuation and the fire station personnel coming to check that everything really is ok. Very, very embarrassing, but sort of funny at the same time. One of the bigwigs in the building, completely of his own volition, sent out an email to all staff saying how well the fire drill had gone.
