I was pretty fortunate that my old employer was closed on the big 3 major holidays, I still had to go in for a few hours for maintenance stuff but I was always amazed at the amount of people who'd try to get in, and how traffic went from non-existent to practically normal traffic over the last few years. Thankfully we never did Black Friday sales so it was usually a quiet day for us. I just don't understand the desire to stand in lines and deal with that many people to save a couple bucks.
