An appropriate cartoon at War on Guns shows how a store can quickly lose business.
When I was on the hunt for a dive watch, I got the idea to go to Jared because they carry a much larger selection of watches than the local mall. I had never been to one, and as my hand touched the door handle I spotted their "No Guns" sign, making me about-face on the balls of my feet and get back into my car.
The logic of such signs may make sense to some people at first glance, with the desire to not have armed maniacs visiting places that sell expensive jewelry, but they have never considered that said maniacs don't care about the signs during the course of armed robbery, if they are even literate enough to read them to begin with. Like it makes sense to prevent a scumbag from using a firearm to violently steal from a store by posting a sign telling them not to.
But why would someone neeeeeeeed to carry a gun to shop for jewelry? CTone, it just seems so silly! Well, consider that a shopper going into a jewelry store, where merchandise has heavier price tags than say, the dollar store, is very likely to have large amounts of currency on their person; and people leaving the store are likely to have small and highly valuable property in their possession. If you try to think like a criminal, if you were looking for the maximum payout for the holiday season, would you be looking to select a victim from Jiffy Lube, or Jared? Making sense now, huh?
Same thing with banks. Only a criminal would carry a gun to a bank, I've heard it said. Well, that's thinking like a criminal too, as people that harbor that mindset don't see a gun as a defensive weapon for preservation of life, but as an offensive tool to hurt somebody. Shame on you. Sit in a bank parking lot for a couple of minutes and watch who goes in and out. There is a high likelihood that those individuals are flush with cash. A Piggly Wiggly, not so much.
