Through the front

I do not want to waste any more time than I have to and so taking a rock I hurl it to the side by the zombies hoping that they would take the bait. They do take the bait and move towards the sound and in the mean time I sneak through behind them and see that the door to the shop was chained from the outside. There is no lock on it, maybe because the zombies were brainless, so taking down the chain I walk in. Once inside I chain up the door from the inside just in case and start walking around seeing what is left in here. I see a few decent bits but nothing too great but it is the end of the world so I can't afford to be picky. A noise came from the managers office, followed by voices. I walk towards it and I know its two men.
