At my old store we were not open on Thanksgiving day or Easter before we became a Supercenter.  My old store has been a supercenter since March of 2002 and is now open on Thanksgiving and Easter.  My new store is a supercenter so we are open too.  People shop after they get done eating to see if they can get one of the Blitz deals early.  I have had people ask me if they could get the camera on Thursday because they did not want to wait in line.  I always tell them if you think I am stupid enough to risk my job to sell you that camera today then you are crazy.  LOL  I even tell them if I was stupid enough the register would not let me anyway.  Now that we close at midnight it will be a free for all to see how fast people can get in the store and find what they want.  In a 24 hour store people can come in early and scope things out to see where they need to be for what they want.  It is incredible how shoppers think we are the most stupid people on the planet.  (Well at least I HAVE a JOB) :D
