What is it about break room “community food” that turns otherwise civilized adults into savages?

Really? You couldn’t just take the whole doughnut with you?

Here’s the thing: no matter which setting applies, no one will go family dog to your table scraps.

Toss it now or toss it later – it’s going in the trash once you’ve fingered it all up. So please, people, just take the whole doughnut.
