Speaking of queuing..
You forgot the Black Friday tradition for idiots waiting for hours in the freezing drizzle outside of Wal-mart or similar at 5AM for the doors to open so the first 50 can grab a child's bicycle or Tickle Me Elmo for half price. There have actually been stores with a police presence outside to maintain order when the doors open.
Now grocery shopping is a different story on Black Friday. Everyone is eating leftovers after the US Thanksgiving holiday, no one wants to face the thought of buying/preparing more food, and all the idiots are Christmas shopping. So there is practically no one in the grocery stores. It's blissful.
