From my experience in taking pictures in places like Target, Walmart, etc. I just stand there and take any picture I need. It seems no one even pays attention, cares, nor say anything. I think they see things like that so much, they don't think anything of it. I think it's a lot in how you carry yourself. If you act like you belong there, they don't pay attention. But, if you show reserve in any way, you stand out to them. I've even pulled up a top stock cart, climbed on it, took an Aerial photo, and pushed the cart back. Staff and customers just kept walking around me. I don't even think anyone even looked at me.
