That's awesome. If open carry becomes legal in TX, you should have an open carry promotional discount as well!
I love it when small business owners stand up for freedom. When I was in New Hampshire last year, I saw a sign at a business that said something like "Hey Obama, I built this business ALL BY MYSELF!" While not 2A related, it was still a nice nose-thumbing at our freedom hating president. I wish I had stopped to take a pic.
