The biggest problem with these sales/stores/customers, is NO ONE considers the people who have to work at these stores.

I used to work in a 24hr Walmart SuperCenter. Had the misfortune to work 2 Black Friday's before I left there. I can tell ya, people are animals when it comes to BF. Sales don't start until 6am, but the store is open so people are in wandering around for hours waiting for the sales to start, and of course they think they can go ahead and get the sales items because "Well, the store IS open!" They will argue with you, scream at you, call you every name in the book if you dare to tell them they can't have it until the sale starts. Then when it does start, get the hell out of the way because they will push, shove, punch, rip it out of someone else's hands, and in general be the rudest most obnoxious people they can be. Ugh. I don't even leave the house until BF is all but over.
My wife and I were talking about this when we found out the local grocery store is now staying open all day on Thanksgiving. That is really not necessary. Let these people have the holiday. Of course I think Thanksgiving in particular gets the short shrift in the rush to the December holidays.
