Gas was out or running out all over town yesterday at 3pm, every station had a line or it was closed. When I drove to work this morning at 4:30am, both 24hr stations I drive by had gas and were open. An employee who left yesterday for a long commute to Brevard barely made it home, but after he used his lawnmower gas to get back to work today, he reported every station he saw also had gas and was pumping again this morning.
I don't think there is much to it beyond humans acting irrationally.
