Hi Marty,
Here's the text from

Basically, private places can post a sign, but it has no force of law. They can ask you to leave if you are discovered to be carrying, but you have not committed a crime. Nothing like 30.06 in Texas.
See section 4 a & b below for specifics on building with security screening..
I hope all goes well with your granddaughter.
Peruse the link for the complete facts.
