I use a hybrid version of the technique recommended by the other responders to your comment: Take the big hardware with me, and ask my neighbor to watch the remainder of my stuff (usually my bag, power adapter, and a couple of sketchbooks). It's just imprudent to leave two grand sitting out on a table, IMO.

As for restroom cleanliness, worrying less about that is one of the many benefits of eliminating caffeine from my diet ;)
