What are you allowed to keep in the fridge at work?

Everyone has been asked to label food and I found a cheesecake in there with no label, I think it was up for grabs.. but then the owner was like no no no that cheesecake is MINE. I was so disappointed, but happy for the person who kept their cheesecake?????? <br><br>It made me wonder, what can you keep at work? I keep a little jar of almonds and a protein bar in my desk, that was the cheesecake ((labels don't matter I suppose), and I have heard of people keeping prunes and coffee creamer in the fridge. So, what else is out there?
