As if printers didn't have enough problems on their own, you also have to deal with maniac coworkers who can't operate the simplest task on them. This note is funny, but again, a bad idea. As we all know, many people are not fluent in sarcasm.
And you thought roommates were the worst. Coworkers stealing food makes less sense because they're presumably earning nearly as much money as you. Being passive-aggressive is the best method of dealing with both.
This had to happen multiple times for a sign to become necessary. Maybe if certain people (ahem, Debbie), weren't stealing such a ridiculous concoction of food, they wouldn't get so nauseous. Then again, I guess it's nice of them to technically give the food back.
Human are interesting creatures. When presented with our own flaws, instead of recognizing them and trying to improve, we lash out at others' flaws and try to say they're worse. Why can't we all just get along?
