I was mostly thinking about how prepared you are with supplies and the like, but what would you do if you where at work?? My plan has a lot of running in it and not much beyond that.
I work at a Office supply store located in a strip mall. There a local Grocery store, a Wallgreens, and a few resturants around. I would assume we get hit pretty hard early when people start swarming in for supplies and safety. Granted that our security gates are worth to shitless It wouldn't hold, when the dead or the living swarms. But I do have some epic ideas for makeshift weapons.
Like making a spear out of a broom stick, ducktape, and box cutter blades.
I really doubt that we'll be able to establish a defense of any kind, and I'm not even sure if the other stores are willing to cooperate with us.
