Great thread and great responses

Nothing for me to add except for a question. In real life it doesn't go as smooth as doing this or deciding that. if the group in the building is rather large , then some will not follow your decisions or may even challenge you, regardless of what the boss says. The boss may even have different plansd of his own like the ship captain who deserted eveyone and escaped in a lifeboat ( forgot the exact details).

But for the sake of the scenario and to be able to fcous on priorities, let's say that some group or groups decided to follow their own plans by leaving the building , or calling other from other buildings to join or whatever.

Then what ?

I think for myself if someone decided to leave I won't care. But if someone is calling others whom I don't know, I would be careful not to reveal everyuthing I have stashed in the building for my own survival. I do have a small stash of food/drink/tools that will not support many people.

About fire, it is not that critical in our office building. It is a modern building but we have some spacious "balconies" and some metal waste baskets that so appropraitely are used for "paper recycling". They will be already full of waste paper ready for burining. We can use for fire if we had to cook, though unlikely. But who knows we may need to boil water for sterilization.
