A bar. No, seriously!
I haven't done it myself but, there is a place called 'The Sportsman" in Sonora, CA that features a working bar and gun store. I have yet to buy anything from there(prices high and limited selection), but make it a point to take friends there just to have a beer and a laugh.
They've had dual status as combined sales since the 1940's.
The owner/bartender is a kick in the pants and says she has CCW but rarely carries it while working. I asked her why, she said "Honey, most of my regular customers have their own and everybody in town knows it."
