Ditto Sam1911.
If I'm carrying concealed, I usually conceal well enough that someone who isn't looking for a gun won't know it's there. Sometimes, I do better. Sometimes, I don't care.
My main priority around town is simple: if the grocery store doesn't like me to carry a gun, they're going to have to look for it, and confront me about it. Since the only reason most businesses have any problem with someone carrying is to keep other customers from freaking out, the LAST thing they're going to do is call attention to a gun that most people wouldn't ever notice.
In some situations, like the bank, I will conceal more carefully because I buy into the "tactical advantage" idea. If someone with violent intentions does rob the bank, I don't want him to think I'm a plain-clothes cop and single me out to be shot. I'd rather be able to make my own decisions and take my own initiative when, where and if it makes sense, or keep the gun hidden as long as that makes the most sense, not be forced into action at the crook's discretion.
But just for going around town, I conceal because it helps me avoid inconveniences, not because I give a crap about hiding the gun.
If someone is uncomfortable around guns, I'm not sure what they're doing in Idaho...
