Nationwide there's a new kind of cooking store where you go there, and prepare the raw meals, then take them home and cook them over the next few weeks (you freeze them). I wanted to give it a try and scheduled a visit. Wore my GSSF range officer polo (no specific reason), and the couple there making their own meals both asked me where and what I shoot. Turns out the short haired husband was LEO, and wife shot also. Surprised the heck out of me as I have few fun related shirts, and had never been asked about them or shooting.
So, one way might be to wear gun related clothes.
