A little back ground, I have been carrying concealed for a little over 10yrs now. Got my permit when I turned 21. For those 10yrs, I have never OC'd. Well I got a part-time job where I can carry. I had to stop by the bank Saturday. I walked in OC'ing, waited in line, deposited my check and left without a hitch. While I was in line they kept saying code 1, I don't know what that means. So my first time OC'ing was at a bank This bank use to have a no firearm sign at the door, but it's gone now.
