If I go right, I have the mesh case for my wireless mouse. Go a little further and a I have a hard backed book, which forms my working diary. Useful stuff, though in the event of a zombie apocalypse, BT would probably see fit to have the phones working for a change.
In the left hand, I can quickly grab the petty cash tin, which has about £10 in small change. That should help in some way.
If I can fight to the door, I can get the umbrella or a bread knife from the kitchenette. You're not going to be silly enough to fight off wave after wave of zombies with just the first weapon you grab, are you?
