I was thinking this way about a Taco Cabana argument on another board where a compliant 30.06 sign was posted behind the counter. If it was not at the entrance it doesn't count, right? But the Penal Code doesn't say it must be posted at the entrance(s). At least not that I have found.
Unless you can show me elsewhere in PC30.06 or other sections of Texas law that it states that the sign must be at any/all entrances.PC 30.06
(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.
