Key ingredient for chicken noodle soup, an old fashioned cure all.
But the soup aisle was fully stocked. And frankly, folks in this town don't cook anything that complicated. My guess is the chicken section just started getting a bit low, and everyone grabbed some thinking it was their last chance.
I'm very glad I was at the supermarket to see the frenzy first-hand. It's a rare sight. I'm familiar with some theories of human behavior, but to see it in action is still amazing.
