For a CHL holder to be prosecuted for carrying a handgun in a place that does not allow it (other than those expressly made illegal), the sign MUST be: a card or other document on which is written language identical to the following: "Pursuant to Section 30.06, Penal Code (trespass by holder of license to carry a concealed handgun), a person licensed under Subchapter H, Chapter 411, Government Code (concealed handgun law), may not enter this property with a concealed handgun"; or (B) a sign posted on the property that: (i) includes the language described by Paragraph (A) in both English and Spanish; (ii) appears in contrasting colors with block letters at least one inch in height; and (iii) is displayed in a conspicuous manner clearly visible to the public. So this means nothing to a CHL Holder: But this sign should keep CHL holders from bringing their handguns in: So to answer your question, the only way to know is look at or near the door of the store and see if they have a sign compliant with Section 30.06 of the Texas Penal Code.
