I can all but guarantee that someone you know and care about is planning to go shopping on the day after Thanksgiving. You need to intervene.
Black Friday is a contrived, customer-hostile, bait-and-switch, potentially deadly symptom of what's wrong with bricks and mortar retailing. A handful of grotesquely low prices on a smaller handful of products are advertised as "doorbusters," and we've been subjected to years' worth of propaganda intended to associate the day with shopping deals, however imaginary.
