Reminds me of the AC at a large multinational Indian company I used to work for - the only way to adjust the temperature or airflow was by calling a service desk operated from, you guessed it, India. Bit of a nuisance when it's -10 degrees outside, while the support people are working in excess of 30; they just didn't understand why anyone would want anything higher than 16, nor were they willing to let it sit at a reasonable temperature.

Meanwhile, you have stores like CircleK that, at least in most of Europe, operate a large fleet of externally connected monitors that keep track of temperatures, but staff themselves adjust the fridges and freezers. All you get by breaching those would be a bunch of temperature readings. Great in a pinch if you're looking to buy an industrial fridge or freezer, not so much for anything else.
