I routinely carry in both bank and credit union, many different branches, sometimes CC and sometimes OC. The odds are in favor that I'll be OCing in banking institutions, more often than CCing. Most of the banking employees know me now, if only for the reason, "That's the one that's always got a gun." They are all very kind, never "antsy", very amicable with me, never once questioning me. Just thought I'd add this to mix.
