I would like to say that I have an amicable solution.
I have a small horde of non-perishables. Enough for two people, for a week, easily.
I live in an apartment style university dormitory.
I would shuttle my food supplies up to the third floor along with anyone else smart enough to come and all of THEIR food.
We could, thereafter, pile all of the cheap furniture into the narrow stairwells, and fend off the zombieness.
Problems that arise:
College students, despite my preferred reality, are quite stupid.
Someone would try to leave and break our barricades.
MOST students wouldn't have their own food stashes.
If the barricades were lost, someone would go onto the roof, and lock the door, so no one else could follow.
Lack of weapons. The best I could do with what I have is form a rough shield, and a frying pan.
I know enough girls in this dorm...a few hairspray cans and a stolen lighter or two from the smokers would make a handy improvised flamethrower/bomb.
In any case,
Without the option to relocate - I would likely be screwed.
EDIT:
My dorm has metal doors and frames but massive front facing windows *rolls his eyes* The designers of this map had no forethought of zombie apocalypse.
EDIT 2:
I just remembered that MY room has a floor hatch that leads UNDER the dorm, with no other access points...
