Firstly I would grab the cricket bat and look around for my t-shirt in hope of my keys being there. If a zombie got within 5 feet of me I would smack it oops up side the head and as soon as I found those keys I would be out of there. I am thinking that my friends would have guessed they are in danger by now and would follow me whilst getting to the car, I would get to the closest police station and get a weapon. After this I would head back home (better to rid myself of dead family members first) and then head for the supermarket to stock up on food and drink.
If the zombies are slow enough I could run to check out the situation on numbers, after this I would head for the radio hq in the town centre and get out a message.
After that I would just fight for survival.
I must say, I'm a little disappointed that you didn't find a use for more of the stuff I gave you. The net, for example, sounded useful, plus you only assumed you could find your keys, didn't consider the option that you might not be able to find them, due to the zombies every where.
You also left the Guinness behind. Naughty, naughty...
Also, considering I gave you a pretty concrete description of the starting area, I had hope for more concrete descriptions of where you would go; for example, do you even know where the police station is?
Considering the early state of the Zombie attack, I'm not sure robbing the Supermarket is a good option, or attacking a police station, as the end result would most likely be you, in a jail cell, surrounded by zombies.
Honestly, I would give that response a C-, but only because I am in a generous mood.
.. Assuming I lived in NY.
Abandoned office building... Hit the stairs, go up quickly, move through doors and block the way so the zombies would be slowed down. Tell the lady it would be better to split up and try to make it on our own. Attempt to move somewhat silently, so as not to attract much attention, hoping that she will have less success in doing so and thus attract their attention. If by chance running through a canteen, grab some solid knives.
Figure out where the fire is coming from, and try to ensure that the zombies have been lured at least a few floors up, then trying to make way into a ventilation shaft. If possible, escaping that way in another direction than the fire.
This would all need to be timed somewhat with the approach of the fire and the speed of the zombies, but should be relatively possible? Depending on the building, of course.
... Did I do something wrong? *chibimazzelhface*
I would have to call that an epic fail there Z, my apologies. Heading up, and crawling through air shafts, in a building that is going to be on fire in thirty minutes is a death sentence, the best possible outcome being a bar-b-que for the zombies.
If you do pass through a building looking for stuff to help you, if the only thing you grab in the canteen is knives, you are missing a lot of potentially useful stuff, not least of which is water. The odds of finding a handgun of any type in this situation is minimal, but there are still things of value to be considered.
MY RESPONSE TO THOADS SCENARIO
At the very least, anyone who has taken this scenario should have mentioned that they look at the directory to see what resources might be available. Is there a Doctors office? Is there any kind of business that might have fire-arms? Worth checking, but searching the building at random is a huge mistake. I would use this information to maximize my resource collection, working from the highest useful floor down, but with the fire so close, I'm not going any higher then the 5th floor, unless something really useful might be within reach.
If the power is still on, (and I think there should be a good chance of that) I look for the security office, if this is a modern building, the heavy set lady could sit watching the monitors, while I take a walkie-talkie, and explore. (There might also be hand-guns kept there, and the door should lock.) She could warn me about zombies in my area, and the proximity of the fire. I would not cast her aside for no reason, she can carry stuff, and she is an extra set of eyes. This is no time to waste any resource. Besides, after a few months of surviving the zombiefied landscape, (if she does) she will lose a lot of weight, and be an even better ally in the world to come.
Speaking of the world to come, if there are any jewelers, and the riots began during the day, I would try to get a few handfuls of gems. They don't weight much, and there is always some idiot who thinks a shiny rock is worth more then a handful of bullets, or a can of gasoline. If the riots occur at night, I assume all the calues are locked in a safe, so i would not waste my time.
What I did after this would depend on the situation. If I could hide in the basement, I would move backwards through the burned area, once I returned to the surface, thinking it a safer direction to travel.
