That was pure panic. I live in the gulf coast. Anytime there is a minor chance we are getting hit by a hurricane people panic buy and suddenly there isn't any water on the shelves anymore. You'll see average folks with 20 cases of water being shoved in their massive SUVs for a family of 3.
Sure. However, I bought a large pack of toilet paper when I saw headlines about hoarding in HK, before the shelves began to dwindle here, and thus dodged the whole thing. That it was basically panic is neither here nor there: paying too close attention to far-off news did actually pay off in a tiny way.
