That's is exactly correct. As I said, 30.06 applies, 30.05 does not. But, there's a very significant detail as to why you want to post the sign instead of relying on the verbal notification clause and why it gets you sued... Consistency. Until you post a valid 30.06 sign at the door, every time I come in the building you are going to have to catch me and tell me that I have to leave... which will be a special trick if I'm carrying concealed. And god help you if you toss me out when I'm not carrying. You can't file a trespass warning on me because I'm exempted from 30.05... and you can't nail me for 30.06 because I'm leaving every time you tell me. Every time I successfully carry in your establishment without being kicked out I'm setting precedent that you arbitrarily enforce your policy, because let's face it, if you were serious about it you would have posted the sign. So yeah, a gunbuster sign means bupkis in Texas.
