I've OC'd out there many times. I was once the recipient of an escort all the way to the door, and another time I was on the business end of a felony stop in the parking lot. I have not, however, been told that I was not allowed back in the store. The manager told me (after the felony stop) that they weren't the complainant and that I was still OK. These were both a while back and I haven't had a problem there since, I still go there with some frequency.
