New Fridge Found to Operate Much Better Than Broken One

So in a repeat of the "boy this milk seems a bit warm" incident of a few weeks ago, our fridge decided to shut itself off some time early this morning, only this time it didn't turn itself back on in the afternoon. Props to Ridgefield Maintenance; they had a guy over less than a half hour after we called it in after work, and about ten minutes later a new fridge arrived. We figured it was just gonna be from the fridge pool somewhere, something that had been removed from someone else's unit and repaired, but it looks like this one has never been used. It's not exactly state of the art, but it's got a little more room and a much better layout on the inside, and it still had a sticker on the side. Our old fridge had some pretty heavy mileage on it, so the upgrade is pretty sweet. Really, the only downside is we had to chuck some food that got too warm for too long, but the grand total wasn't too bad. And now we don't have to worry if there will be any more warm milk incidents. All's well that ends well, I guess.

Have They Tried This Already?

Soda coolers in takeout restaurants: why don't they have motion sensors, or timers, or something with even the tiniest bit of sophistication, that makes them able to decide that their off the clock and at the very least shut off the damn lights, preferably raise the maximum allowed temperature a bit. House thermostats have timers so that they don't bother cooling the house as much when everybody's asleep or at work; you would think the concept would have filtered down a bit. Maybe they tried it and nobody bought them? Maybe the technology wasn't quite there and it didn't work out? I demand answers.
