Just an interesting story relevant to this discussion.
My son worked for a "financial" institution locally, while waiting to enter the US Army after he graduated from college.
They prohibited concealed carry at work. Later on he was asked to do "field calls" to those who had defaulted on their loans (you can see what kind of financial institution this was) and his supervisor asked him if he had a CCW (which he has) and then advised him to carry!
I thought the double standard pretty funny but he did carry and one of the "customers" he visited in some trailer park threatened to turn his pit bull loose on him. He didn't do it but my son said he was very glad he was armed when the guy made the threat.
I think he might find the Army less dangerous than his last job!
