Yesterday we were in Tucson amd stopped for lunch at a well known chicken take out joint. There were two of us in the lobby waiting for our orders, a black woman and me. We both got our orders about the same time. I let her approach the door ahead of me and tried to push it open for her. She opened the door and said go ahead, I have the door. I thanked her. She thanked me and we both went on about our business. No rioting took place. FWIW.
