When I worked at a railway station, the emergency phone in the multi-storey car park's lift automatically dialled the phone in the station supervisor's office. If that call wasn't answered within a couple of minutes it was then automatically sent to the supervisor's mobile phone, so that it couldn't possibly be ignored. We pointed out to senior management that the flaw in the system was that nobody actually knew how to release people from a broken down lift if they received an emergency call. It took a year before we were given training in the correct emergency procedure.
We then pointed out that the procedure we'd been given meant getting into the motor room for the lift, but none of us had a key. It took another year before we were supplied with keys.
Eventually the day came when the lift broke down, with a passenger inside it. He picked up the emergency phone, so that we could take his call and spring into action. Unfortunately he found that the line was dead because nobody had bothered to pay the mysterious phone bills which the company had been receiving, simply addressed to 'The Lift, London Eastern Railway'.
(The guy had to use his mobile phone to call the fire brigade. As he was a solicitor, he then sought hefty compensation from the rail company).
