"Amusing, but in that instance, why would he not have told the real reason?"
Presumably because he had done so and been ignored.
Most of these devices used to come with a night mode specifically to prevent such things happening and users would switch them off at the wall despite being specifically told not to.
We would find that we could happily bill them $140 per call out, just so they could save 1c in electricity.
