TABC rules state that an establishment will have it's liquor license revoked if the license holder permits an individual to possess an unlicensed handgun in the establishment.

When an individual carries concealed into an establishment that sells liquor, the proprietor is unaware of the gun. If any issues arise, the establishment's license is not in jeopardy because, given that the gun was concealed, they were unaware of it and cannot be penalized.

In the case of open carry, the moment the individual steps through the door, the proprietor IS aware of the gun because it's in plain sight. If they allow the patron to remain in the establishment without verifying the legal status of the handgun, they are in violation of the TABC regulation prohibiting unlicensed handguns on the premises.

They are legally obligated to ask if you you have a LTC per the TABC, this gives them the authority to ask for your license.

In short, if you're going to open carry in any establishment that has a liquor license, be prepared to show your LTC. If you have an issue with this, cover your weapon, leave it in the car, or don't go there in the first place.
