I had to visit the store yesterday afternoon, and I was surprised by how picked over some of the shelves looked. You could certainly tell that it was the end of a long weekend without 100% of the usually scheduled deliveries, which is kind of scary.
A common theme in a lot of TEOTWAWKI fiction is how quickly shelves will empty at the grocery stores...and it's easier to believe on days like today. This was just a normal holiday weekend, with no special driver for intense shopping, and a lot of items were noticeably lacking. For the most part it was 'fresh things'....dairy and bread...but the frozen items were picked down to about 50% also.
Just an interesting real world reminder of why it pays to stock up...and that we are just 3 meals away from a revolution.
