Sorry if I'm getting a bit off topic - I thought you might find this interesting:
The only signs I obey are those that meet the requirements of what meet the requirements of a "no guns allowed" sign by the Texas Gov't; oddly, it's called the 30.06 sign (either due to some incredible timing on the introduction of the provision or just plain, but kind of cool, luck!).
The onus is on the business owner to comply with this:
Concealed Handgun Licensing Bureau
PROHIBITING HANDGUNS IN A BUSINESS OR OTHER ENTITY
In order to provide notice that entry on property by a license holder with a concealed handgun is forbidden, Penal Code Section 30.06(c)(3)(A) requires that a written communication contain the following language:
"PURSUANT TO SECTION 30.06, PENAL CODE (TRESPASS BY HOLDER OF A 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."
"CONFORME A LA SECCIÓN 30.06 DEL CÔDIGO PENAL (TRASPASAR PORTANDO ARMAS DE FUEGO) PERSONAS CON LICENCIA BAJO DEL SUB-CAPITULO H, CAPITULO 411, CODIGO DE GOBIERNO (LEY DE PORTAR ARMAS), NO DEBEN ENTRAR A ESTA PROPIEDAD PORTANDO UN ARMA DE FUEGO."

Penal Code Section 30.06(c)(3)(B) further states that a sign must meet the following requirements:
1. includes the language described by Paragraph (A) in both English and Spanish;
2. appears in contrasting colors with block letters at least one inch in height; and
3. is displayed in a conspicuous manner clearly visible to the public.
Please note that while the language provided above may be downloaded for convenience, it does not meet the requirements of Section 30.06(c)(3)(B) and may not be used as a sign.
So any of the "No guns allowed" or the like can, legally, be ignored.
Oh, you'd be surprised by how many business don't meet their legal obligation re: the 30.06 sign. Then again you'd probably be disgusted by how many do.
Take care,
