A lot of companies have no-gun signs posted. I often shop elsewhere if at all practical. And yeah, we ought to verify whether this is corporate or local store policy. IF up to the local manager, you might have influence on him, even if he is an anti-. A locally owned hardware store near one of my comm sites was posted. I really need the part that day, but I spoke with the owner. I explained the illogic in posting, as crack-heads looking for a buck or a ticked-off customer neither care about that silly sign if they are there to cause harm. It only tells them that it is a kill-free zone and that we law-abiding citizens won't be able to defend ourselves. In a tight economy where he is competing against Home Depot and Lowes and folks like myself will opt to go there where I CAN defend myself, it's not smart idea to post against gun-owners
He sort of shrugged it off, but a month or so later, the sign was gone. He thought about it, I'm sure. A LOT of private owners will to if given a reasonable argument how silly those signs are. Still not sure about Grainger. May swing by there in the next few days and see if it is posted. If so, maybe ask the manager if it is company policy or of his own choosing.
