I live near Chicago and although I am a nervous shopper, I still manage to shop at most of the stores that you mentioned. I have never gotten any of the results you have gotten. I'm not calling you out as a liar or anything like that, but I think that you are being to hard on yourself. You must be doing something that is letting your friends know. If they are following you around then they are not your friends at all. I'm in the closest about my dressing and none of my friends know about me but one, and I told her years ago.
