Technically..... but its easy to do and it really depends on the store. I know and have known quite a few employees that do and I'll admit I did it also when I worked there. I've met wal-mart employees from a few different states, and some could get away with it and some couldn't, we were told not to but sometimes it pays to be a rebel, and on black friday, sometimes you have to be a rebel. Of course in montana we don't have problems or issues with security or police or anything like that so black friday usually goes pretty smoothly. You just have to deal with the rude people that are usually running on no sleep.
