Anything but canon
(covers information that is anything but canon)
A break room was a room in a building that was used so that workers could take smoke or coffee breaks.
According to an account that was anything but canon, one particular species often cooked their leftover fish in the microwave oven in break rooms. In fact, Bragu, a member of that species even desired to do the same in the Federation. (VST: "Worst Contact")
