Sharing is caring
Sharing a desk with someone else is uncomfortable for everyone. There’s not enough elbow space, and you can’t spend your time surfing the internet without fear of the other guy tattling on you. However, you can make your uncomfortable situation much, much worse if you drink from the other guy’s mug.
That’s what this poor soul did. He had no idea where he left his mug and assumed that the one close to him was his. He took a big gulp of tea, only to find his coworker staring daggers into him as soon as he set the mug down.
