To me this whole issue is a question of integrity - on my part individually and on the part of the 2A movement as a whole. They said directly that they do not want us carrying in their establishments; the fact that they will still serve us as normal and not kick us out for carrying is beside the point. Since I rarely go out in public unarmed and because of my integrity, it is in my/our best interest to honor their request and not patronize their establishments. I am not boycotting them, I am simply honoring their request. The consequence of honoring their request is no money from me.
Besides, I found a couple of coffee shops that have waaaaay better Java anyway.
