Fuck aruging. Just knock the bitch out. BTW I work for WalMart and security would not have made you move. After all that arguing, you both could have been checked out and on your way. Me personally, I'm a cashier. If a customer comes from another angle and beats another person, then first come, first serve. If you have an issue, talk to management. Otherwise it isn't that fucking serious. I've actually opened my lane up before and pulled a customer from another line to come on and had other customers try to beat that person. I block off their carts way of passage until that customer I pulled can get in my lane. I'm sure customers think I'm a bitch, but I RUN THIS SHIT!!!
