The carrying of a concealed weapon on these premises is prohibited"I say "stupid sign" for 2 reasons: 1) Concealed is concealed, so how are they to know? 2) The target is misdirected. A criminal is going to ignore the sign and do his deed anyway.
However, as a lawful gun owner, I dutifully went back to my car and disarmed.
While there, I took the time to ask about the sign, and had a nice dialogue with the teller about guns. She grew up in an 'anti' household and admitted fearing guns, but is married to a Marine and said she wanted to get over her fear. I told her that guns were fun, and she should seek out someone to help her learn about them. All in all, a good contact.
Now tomorrow...I might just go into that branch again, openly carrying, as their sign expressly forbade concealed carry. :)
