Reminds me of a mishap at uni. I lived on campus with about 300 others in my accommodation. My block had 3 floors, 2 wings with 20 students in each. Each wing had a microwave amongst the 20 students.
One day a girl on the far wing middle floor decides to cook rice for lunch. She had most of the ingredients (rice) but forgot the water. 8 or so mins later the smoke alarm went off and the entire block bailed, and as we gathered outside people were coughing on their way out. The fire brigade deemed the place safe to enter, but that was a broad statement. On entering the bottom floor of the opposite wing, the stink hit you in the face and it was borderline difficult to breathe. The wing itself was honestly borderline not enter-able. The smell was so strong people running through it with their nose under their jumpers actually stank of the burnt rice for the rest of the day. Members of the wing bolted to their rooms and shut the doors. For those that left their doors open (against the rules in a fire), well, they paid the price. An hour later I entered the wing and their were no fewer than 10 pedestal fans lining the wing directing fallout to other areas.
The wrath didn't end there. I was lucky enough to walk past some Zimbabweans the next day cooking some chicken drumsticks in the microwave for the first time. One of them was gagging and choking, the other had a look of severe distaste as they were smelling and observing their drumstick. The tea room smelled strongly of burnt rice. From that day onwards the microwave would destroy any flavour of food which may be placed in it and curse it with the horror of burnt rice. The wing members did the logical thing and swapped it with the microwave of another wing, and for the unsuspecting who weren't aware of the incident, they couldn't identify the smell and know not to use it. It was a force to be reckoned with and left destruction in its wake.
And guess what the offender was studying? Law.
