Well, I've been blacklisted from a Gamestop. A few days ago I went in and bought up a few pennied guides. The cashier was adamant about not selling them. So I called corporate and spoke to someone who approved my purchasing them. Today when I went, the same guy was there and would hear nothing of it. He treated me with absolute contempt. Made my stomach turn. I won't be going back.
The first rule about penny guides is that you don't talk about penny guides.
The store has no right to sell them to you and calling corporate just screwed anyone who might have gotten them at that store because they were friendly with a store rep. Now that you called, that store was eyeballed by the DM/RM and the store manger probably was read the riot act about selling/giving away penny items.
All you did is screw yourself and everyone else around you. Good job.
