Depends. If the community has treated me well and I can afford it, I'll be at the station personally authorizing each pump, it's price and the amount to be pumped. My employees will get 'hazard/disaster' pay as well.

Some may get unlimited gas for free. Some may get no gas at any price. Some get rations to get out of the area at a high price.

Disasters and local communities are personal. I'll give a highly personal response.
