I carry a concealed weapon everywhere I go so I'm what you'd consider "gun friendly".
I get aggravated when someone just leaves a gun sitting around. Yesterday I got in a customers car, there was a Kahr 9mm (in a holster) stuck between the shifter and the park brake lever. I didn't know this customer, and they don't know me. Some of the people I work with would have freaked out had they seen the gun in that car. (FWIW the same people would freak out if they knew I had (secured) weapons in my truck in the parking lot.)
A couple months ago I found a Ruger LCP sitting on the back of the sink in a grocery store bathroom. I called the Sherriff and stayed at the bathroom until a Deputy arrived. What if a young child had found it, and thought it was a toy?
Anyway, rant over, and a bit of advice. If you carry a weapon in your vehicle you need to either remove it, or secure it if someone else is going to be in your vehicle. Also, if you carry a weapon, either concealed, or open figure out what you're going to do with it if you have to "do your business" in a public restroom. Sitting it on the back of the sink isn't a good play. I put my holstered weapon down into my pocket, then clip it back on my belt when I'm done.
