Short but sweet. This person would put her food in the (only) office microwave and leave the break room while it was cooking. She would never return on time, and would give you crap if you moved her food out of the microwave to cook your own. She’d take anywhere from 2-5 minutes to come back after he food finished.
Attempts to talk to he about it met with pettiness.
And pettiness begets pettiness…
After her food finished one day I waited a minute for her to come back and decided to add a minute to her cook time. After that extra minute was finished, The next guy in the microwave line did the same thing. Then the whole line. In total, 5 extra minutes.
By the time she got back her micromeal was baked down to a piece of charcoal. (We knew she had more micromeals in the freezer so she would still get lunch). Her food was utterly ruined. She looked around for the culprit but we all just ignored her and played ignorant.
Unsurprisingly, she never left her food at our mercy again.
