Extend the Story - Add a Room

You punch into the metal door with enough force to leave a perfect hole size enough to fit the arm that hit it without making too much sound, you feel about a bit for the door knob then feel above it for a second...you feel a weird metal shape and twist it clockwise and it doesn't seem to budge (you could have forced it to though) you try counter clockwise and it unlocks. You're in!

You swing the door open and enter. You see a line of sinks and a couple of stalls to the left, to the right you see a couple of stalls and urinals and a janitors closet, dead center you see a high window (unlikely for zombies to get through, has a good view of the streets but doesn't seem to have a good view of the sun. perfect).

You set the human man down and check to see if you accidentally killed him in the process of bringing him here, he seems fine...no visible injuries, some blood stains on his clothes, his breathing is soft, he isn't too pale from blood loss. He does look like he might need more sleep, with bags under his eyes and maybe some unseen bruises on his body?

You were just about to kick him to wake him up (softly) when a zombie bursts out from one of the stalls.

Stuff it thru the window
