Yes they are. It was in work. We've got a really small office (30 total) so you generally know everyone and its all cool to leave food around. It annoys me because it only ever seems to be my stuff that goes missing, and I'm the only one in the office (As far as I'm aware) that can't get anything else to eat in the local cafe/s etc for dietary reasons. People are lame.
I'm knocking into your workplace with my biggest angry face and shall roar "WHO THE FUCK ATE JONAH'S BREAKFAST????!!!?!?!?!?!?"
