Where I live supermarkets have coffee and smoothie vending machines, so you can have an in-store-coffee while you are buying your groceries. They have it installed to keep you longer in their store, hoping that you buy stuff you didn’t need in the first place.
Simplified:
Having a fridge running is nothing complicated compared to a computer. The compressor and the light inside are the only things that are being powered. Both components work mechanically: The compressor has an electric motor that is running when fed with electricity. Pistons inside the compressor are linked mechanically to the electric motor. The light inside the fridge is operated with a switch that is mecahanically connected to the door. The light is off when the door is closed. As long as electricity is fed to the fridge, it keeps running.
Computers however are more complicated, as they basically are running clocks that connect an event with a time stamp. They can get disturbed easily when several events happen. When a computer is running long enough it can happen that the memory overflows when a specific event is being executed for example. For this reason it is renommended that your smartphone is supposed to be restarted at least one a month, otherwise it couldn’t function properly.
If refrigerators were operated the same way as a computer, like your laptop or smartphone, I bet it has to be restarted every once in a while, otherwise a malfunction would occur. To my knowledge refrigerators are built the same like 40 years ago, albeit with more efficient compressors, better insulation and less harmful refrigerant.
Home improvement stores do the same illogical placement of their goods: If you want to buy a shovel, you would that shovel expect to be located in the aisle with the garden tools, right? Wrong! Of course, it is located in the timber isle, because the handle is made of wood - that’s what they probably thought.
