Most people know how it feels to be cooped up for hours on end waiting for repair men to arrive: they say am when they mean between 7am and 2pm, and they almost inevitably show face with that much-needed-component for the defunct washing machine just after you pop out for a paper; CNG Energy Co of Pittsburgh believes it can solve a problem that wasn’t a problem when women were full-time housewives, and repair men received a warmer welcome; according to the Wall Street Journal, CNG attaches small computer terminals to a radio in service vans, and when the driver sets off, he puts the cursor on the name and address of his next port of call; the radio communicates with a central computer, which phones the client to say the driver is en route; if there’s no answer, the visit is sensibly rescheduled.
