The highlight of my day so far has been thinking the lift at work had broken down (with me in it), and thinking that I would possibly need rescuing. Fortunately/unfortunately it started again with no intervention and no dramatic rescue needed.
But then I wondered who answers the emergency telephone in a lift anyway? I have vague ideas of someone in a control room at the top or bottom of the lift shaft monitoring it's progress, but even I know that can't be the case! So - who does answer it?!
