My experience was rather dull really, which was somewhat surprising. Never went to black friday before myself, but my mother is a shopping addict so it was old hat for her. Drove by target near my house about five minutes before they opened and the line was completely around the store and into the back, so I refused to even try and drove her to wallmart which was even worse. Told her I didn't want her getting trampled in this nonsense and she could do her shopping tomorrow.
Head home and drive by that target and the line had already dissipated so I figure we can try it. Get lucky and get a parking spot right up front, while my mom does her thing I go to the electronics section figuring everything had been raided by now, but find it rather orderly. Wound up getting their lbp3 and lego batman ps4 bundle + an extra controller free as a 'doorbuster' apparently.
Game racks were all unlocked and I picked up the evil within, watch dogs, infamous second son, wolfenstein and shadow of mordor all for $25 each, alien isolation for $35 and thief for $15. Head to check out and every single lane is open, didn't have to wait at all to get checked out; the only line I saw at all in the store was for people wanting ipads. In all I was in there maybe a little more than ten minutes, though I wound up waiting in the car a while for my mom to finisher her crap.
On a normal day at target I'd have to wait ten minutes for an associate to unlock the racks for a game and then fall in line behind a dozen people at the only two checkout lanes they'd have open at the time to pay. This black friday wound up being the most convenient experience I had shopping at a retail store, ever.
