Because it's by far the worst day of the year. Ever go shopping on black Friday? People will fight over items especially items that their kids want for Christmas. People have even been killed over items.
People can get greedy and act that way at times, grabbing things from others. :sad:
Last year someone got trambled to death at Walmart when they opened to door after they were standing there for hours. So this year they are keeping the store open so that won't happen. There's too much emphasis put on the commercialization of Christmas or things like that wouldn't happen
