Our office building’s only elevator was acting up. When I rode it to the lobby on my way to lunch, the door refused to open. Trying not to panic, I hit the emergency button, which triggers an automatic call to the repair service.
Through the speaker in the elevator, I heard the call going through and then a recorded announcement: "The area code of the number you dialed has been changed. The new area code is 810. Please hang up and dial again."
