I see both sides of the equation. if you are a business owner, you are not guaranteed a paycheck for punching the clock and putting your 40 hours in. Your paycheck depends on customers giving you money in trade for merchandise that you have on the shelves, or performing whatever service it is that you do.
If a lawfully licensed conceal carry holder is so lazy with his CONCEALED weapon, that it can be seen by the business owner and every other customer in the place...and it starts scaring customers away because they're afraid of guns, guess what? you as the business owner are watching dollars walk out of your front door, and going across the street to your competition.
I don't see this as anything to do with a barney fife complex. If the gun was visible and the store owner saw it, you can bet that other customers saw it too. if the store owner just quietly says "hey you're showing" and the customer sees that the business owner "didn't do anything about it" then they may still walk right out the door. but if the business owner says 'hey man, go back outside, re-conceal or put it in the car' and other customers see the guy leave, then come back, they will probably assume that the guy put it in his car, and that there's no more weapons in the store.
at the end of the day, CONCEALED means CONCEALED. If the CCW holder took his obligation a little more seriously and made sure it was concealed, then this is a non-issue, because the other customers, and the business owner will not know that the CCW holder is carrying.
Again, this is not a barney fife complex, or an issue of putting down your fellow "brothers" for carrying a weapon, instead, it's an issue of the CCW holder being lazy and sloppy with his concealment. Why defend him? I've read another thread on here where someone's wife bumped into a man at a chick-fil-a and noticed he was carrying, and she said 'oh, you're carrying' The guy responded back with "100% of the time" and everyone here was calling HIM a "barney fife who thinks he's gods gift to society and needs to learn to respect the CCW and not walk around like a mall rent-a-cop who thinks he's SWAT"
