ELI5:Why do grocery stores use huge rows of open refrigerators without doors, while some refrigeration units at the very same grocery store will have doors which would presumably be much more energy efficient? explainlikeimfive

It turns the whole side of the store into an igloo; making customers cold and uncomfortable would seem to not be a good idea. Or does the laziness of not having to open a door to get to your food product win out over the coldness and huge energy costs? No one has a door-less refrigerator at their house
