Take heart OC brother...
Some of us other PA members had a similar experience. A few of us had enough gumption to call the store manager and get his take. I can vouch for myself that if I had not gotten the answer I wanted out of the GM I would have went to a corporate contact.
When I OC I fully expect to be confronted. I prepare for it mentally and carry information on the subject for those to learn. Because truly to OC is to teach a society that has lost its way.
