Stand where you want to stand and don't move!
I do my best to choose a lane that I will be able to see my stuff on the other side. I also stand where I want to stand so that I can see my property. When possible I stand in a place that will block the sheeple entering the NoS.
I simply ignore the clerks when they tell me where to stand. Once a clerk got in my face because I wouldn't move out of the way. I loudly told him to step back and mind his own business. The look on his face was priceless. I also called for a supervisor when a clerk was bugging me because I wouldn't stand to the side unable to see my property. My groper arrived quickly thereafter and I cancelled the supe.
