Well, we could open our own shops. I visited my aunt up in Wyoming last week, and we stopped at a little restaurant with two signs I adored:
1. Due to the increasing cost of bullets, no warning shots will be fired.
2. [Paraphrasing, don't remember exact wording] Guns are permitted in this establishment. We ask that you keep them holstered unless you need them. If you do, judicious marksmanship is appreciated.
