#16: The Coffee Addict
This OP’s boyfriend has a coworker who loves coffee. Like, he really loves coffee. He loves it so much that he doesn’t ever wash out his coffee mug. Apparently, the nasty brown residue adds layers of flavor that can’t be achieved with a clean cup. If you look hard enough at this photo, you can see bumps and crevices among the brown coffee rings.
Although this doesn’t directly affect any of his coworkers’ lives, it’s still super gross. They’re the ones who have to witness him slurping his morning coffee from this biohazard of a mug. If this is how he treats his work mug, imagine how dirty his dishes are at home. Be right back, we have to go throw up.
