I've always called 'em Snow Vultures. (Snow can be substituted for hurricane, or anything else you might know is coming). Gotta love 'em - always looks like they NEVER have ANYTHING extra on hand, and exist solely on bread, milk, eggs, sometimes canned soup (the smarter ones, since that does not go bad), and snacks. And I guess the toilet paper they also always buy in jillions of rolls is for all the company they always expect, since they seem to be serving the breakfast items to a busload of their closest friends, based on the purchased quantities. And all with a vacant, desperate "it's all about me and mine - get outta my way" looks in their eyes, while feverishly clawing their purchases from the shelves, lest a single carton of eggs, or loaf of bread, escape their tentacles. It's comical, sad, and upsetting, all at the same time. And for God's sake - do NOT get in THEIR way in the checkout line - THEY are in a RUSH, and are the ONLY ones that have to check out/drive home/have things to do!!
With all that being said, I hope all those in the path(s) of any weather are okay, and stay warm, safe, and dry!
