§ 411.20 NOTICE REQUIRED ON CERTAIN PREMISES.......However, it strictly points out that only the "sale of alcoholic beverages for on-premises consumption" is counted toward the 51% tally.
But, like you said, even if they don't post it, it's still our responsibility to know and act accordingly.
What really puzzles me is that subsection(b) says that a hospital "shall" display as well. Does this follow the same logic as "we should know it even if they don't show it"? Even if a hospital doesn't display this sign, can we still carry there? I know that 30.06 says we can't if a proper 30.06 sign is present, but why include this section here?
According to PC 46.035 Unlawfal Carrying of Handgun by CHL (i).... Subsections (b)(4), (b)(5), (b)(6), and (c) do not apply if the actor
was not given effective notice under Section 30.06.
(b)(4) is on the premises of a licensed hospital or nursing home.
So if they do not post on a hospital then you can legally carry there. A bar does not have to post.
