1. Microwave Leftover Fish

There's a reason people don't use the word "fishy" with a positive connotation. I'll stop when drumming on my desk when you stop stinking up the whole office with your salmon, Linda.

2. Burn Popcorn

Speaking of smells that are ruining my work flow, please, just stop the microwave before the popcorn bag turns black. It's not that hard.

3. Make Anything Requiring a Blender

People are trying to get work done; a cacophony of noises coming from the kitchen doesn't help.

4. Go on a Solo Take-Out Run

How dare you go out for take-out and not ask other people's orders? Do you expect to actually enjoy that delicious pizza you picked up while your co-workers are glaring from a distance, choking down their miserable PB+Js? Not cool, man.

5. Flaunt Your Free-Range, Organic, Paleo, Vegan, Soy-Free, Taste-Free Lunch

Cause no one needs that negativity in their life. And yuck.

6. Brush Your Teeth

While nobody likes you breathing down their neck with coffee breath, there's an office bathroom for a reason.

7. Steal Someone's Food

If you take a seltzer out of the staff fridge that doesn't have your name on it, you better be prepared to go to war.

8. Make a Huge Mess

We don't pay you to make things worse, Gary! The least you could do is clean up after yourself.
