What's the most annoying thing about your workplace? (Besides when heroes try to break in)

Sometimes when you're around a lot of co-workers, it's the small things that bug you the most. How often is it that you try to hand someone something (an act often done by a scientist) and the person just snatches it out of your hand? It can be rather grating. The least they could do is not rush to grab stuff out of her hands, risking dropping something hazardous or some parasite or something.

And while she's at it, body snatchers suck too.
