There are rules in the office kitchen. That means you, guy who doesn’t clean up the coffee he spilled, and you, girl who was eying my turkey sandwich. I see you. Not cool. For those who work in an office environment, I’m sure you are aware that there are certain rules of office kitchen etiquette that are just not okay to break.

Don’t be the guy that sends Ross from Friends to take time off on account of his rage because you ate his sandwich (watch the clip here.)
