The office thermostat might as well be that comically large red button that sets off a nuclear war in movies. Take a quick survey of the thermostats in your office and you're bound to come across one that has a screaming yellow Post-it note attached to it with the words "DON'T TOUCH!!!" scrawled angrily across the paper.
It usually happens when, through some marvel of shitty heating and cooling installation, the room that holds the thermostat also features a radically different climate from the rest of the building. The thermostat might claim that the temperature is a comfortable 72 degrees, but in that one room, for whatever reason, it's balmy as shit. Meanwhile, the people sitting in the larger part of the office are as comfortable as can be.
"If not for the part where we all hate life, this would be paradise."
This setup works fine, provided that the smaller room is never used, but unfortunately, that's never the case. Instead, it's usually a meeting room or something, meaning a wide variety of people who may or may not be familiar with the atmospheric dynamic present in the room are filtering in and out all day. All it takes is for one of those people to decide that they don't want to conduct their two-hour meeting in the equivalent of a corporate sweat lodge and turn the thermostat down to, say, 68 degrees. It will still be kind of warm in that little room, but that four-degree drop in temperature might as well be the next ice age for everyone else.
Inevitably, the preappointed office badass, usually determined by a combination of tenure and who smokes the most, will kick in that meeting room door like Dog the Bounty Hunter searching for the deadbeat baby daddy of one of his toothless kids and inform everyone willing to listen that the thermostat is to remain at 72 degrees as stated on the note or hellfire will rain down on everyone in the room.
The people in that meeting will then spend the next hour and a half teetering on the brink of heat stroke and vowing to mess with that thermostat every chance they get going forward.
