I've heard a story of people renting an apartment with locked thermostat to the legally allowed minimum. Tenants would put ice on the thermostat

I heard that was a well-known trick at my old uni dorm. There was a single thermostat for the whole floor so once people figured out where the sensor was, the ones who lived closest to it would often leave packs of frozen food on it.
