So everyone that shops on Black Friday is reduced to a couple of videos of a group of people "fighting" over one of the thousands of items the had on sale?
And in their "defense", it's the people doing it that caused that shit. You have them standing there for 2 hours, once you say go, there's no stopping them. You can easily avoid that by making a line for different products all around the store, instead of just having a free for all. The Walmart I went to had a line in every isle because there was a different pallet of product on every endcap, if it's done that way, you will seriously have no problem at all.
