Wow, this sure generated a comment or two
To clarify two points raised above: I'm neither illiterate nor defiant. But thanks for the kind words.
As others have pointed out, it appears this sign really conveys no useful information at all. Reading the actual laws, anyone with a valid CCW is NOT committing a crime if they aren't drinking, and IS committing a crime if they are. I don't believe it has to be in a liquor establishment, as it's against the law to consume any alcohol, in any venue, while carrying a firearm.
So to me the question then becomes "why did they post it at all?" and my theories would include:
1. They're required by law to post it -- possible because this was not just a made-up sign, but one that had the state seal and the names of the Gov and Lt Gov on it -- I've not seen it anywhere else, so maybe it varies by county or city?
2. The owner meant to post a "no guns" sign and thinks this sign conveys the "no guns allowed" message when in fact, it does not
3. It's posted to scare people into not carrying, even if they have a legal right to, but stops short of actually posting a "no guns" sign -- I'd say this is very unlikely because I can't imagine why someone would be passive aggressive and not just post the familiar sign (which I'd argue comes in three flavors: No Revolvers, No Berettas, or No Glocks).
Thanks for the discussion! I'll now go back to defying laws I can't read anyway
