Not a unique experience, when I walked into my LGS midday a few years back to buy a 600$ item The six old dudes stared at me like I just interrupted their poker game and I had no clothes on.
This isn't unusual at all, but the reason a lot of gun stores don't last around here, is they fail to see the simple truth that there is very little markup or profit margin, in guns. You gotta, gotta, gotta sell accessories. Solvents, cleaning gear, holsters, accessories, all have great markup, and profit potential. Sure, you want to sell guns. But if guns is all you have, I hope you didn't quit your day job.
