Edit: this article has the following statement from the TABC:
http://www.fox7austin.com/news/local-ne ... 9627-storyThe Texas Alcoholic Beverage Code does not contain language specifically requiring businesses to check the License to Carry of patrons who choose to carry handguns into a TABC-licensed establishment. However, under Sections 11.61(e) and 61.71(f) of the Code, businesses could lose their liquor license or permit if an unlicensed handgun is brought onto the premises. Ultimately, how business owners choose to verify the licensed status of a person carrying a handgun is up to them.
(the statement "businesses could lose their liquor license or permit if an unlicensed handgun is brought onto the premises." is probably literally true because it could happen if the business knowingly allowed it, but the fact that this statement is omitting the knowingly is kind of weird)
