I thought this was funny and wanted to share. If it’s against the rules, just delete it. It’s not that important, just something I thought others would find humorous.
Unless the bank is posted as a GFZ or your state prohibits it, carrying into a bank is not illegal. Possessing a firearm on Post Office property, including their parking lot, is illegal, and other federal buildings, but banks are not typically federal, so state laws and business policies are what controls firearms on their premises.
