The powers that be came in a put anti-tamper covers over the thermostats at work many years ago because they deemed it to be too cold in the building.
Later they walked in and found a light bulb hanging by the thermostat and a “too cold” building. Do you know how hard it is to get a bulb the exact right distance to warm the thermostat up to get the exact right temperature?
They were not amused.
Yea, I know, LOL. That was skillful, and I’ve thought about that also.
