There's a ham at my office who's work station is just disgusting.  Keyboard coated in crumbs, big gulp of soda, dust piling up behind the monitor.    These stations have under drsk shelves, and two hanging shelves which close.  I walked by the other day and glaced in while passing. It had one of the under desk shelves open, and the hanging one. Both just filled with cookies and snack cakes. It was eating one, and had moved on to a different one 10 minutes latwr when I passed again.  And this was an hour after lunch.
