Not sure where you are, but after being held at gunpoint twice in 2 stores in Houston (Electronics Store and Lumber yard/Hardware Store)
I figure bank robbers usually have guns and
banks are MUCH more likely to be robbed than electronics stores and lumber yards ... any bank that wants to give a criminal a lethal advantage over a customer must not value my business ...
If a 30.06 sign ever showed up at my bank, I'd :
1) talk to the bank President/manager about the background checks and training required to get a CHL and that being a law abiding responsible citizen is a basic requirement,
2) point out that bank robbers carrying guns in banks aren't required to undergo background checks first and that most ignore signs, but that
THE 30.06 sign does not apply to armed robbers AT ALL any way, it ONLY APPLIES TO law abiding responsible citizens who underwent EXTENSIVE background checks at LOCAL, STATE and FEDERAL levels smilar to the ones Certified Peace Officers/Law Enforcement Officers undergo!!! ...and
3) I'd ask why he prefers the armed robbers over me, (his sign does not even purport to exclude armed robbers with NO license, only licensees/holders of a license)
4) I'd point out that his sign does not exclude anyone ILLEGALLY carrying a concealed handun WITHOUT a license
5) I'd point out that his sign does not exclude anyone walking in with an openly carried shotgun or AR-15 rifle LEGALLY openly carried WITHOUT a license being required (which is perfectly legal, no background checks nor license required)
6) I'd ask him if that's REALLY the sign he wants up to achieve the goals he REALLY has
...(HIs agenda really is to keep out more responsible law abiding citizens in favor of allowing armed people with no backround checks/licenses in?) [ Or, is it that he prefer I bring my AR-15 legally openly carried, next time instead of a concealed handgun?]
then if the sign stayed,
7) I'd either buy a sling for my 20" barrel Shotgun, buy a sling for a rifle I own, OR
8) I'd find someone who really did value me, my safety, and my business more than they value
unlicensed people carrying shotguns, rifles, or
unlicensed criminals illegally carrying handguns ...... just sayin'
Perhaps they were uninformed and just put up the WRONG sign and meant to put up THIS one:
(Why discriminate
ONLY against responsible law abiding license holders who underwent extensive background checks and training? That is what a 30.06 sign does.)
The other thing a 30.06 sign does, is it informs robbers that it is less risky to rob that bank than one which does NOT have that sign ... think about it.
NO bank in my city would be foolish enough to put that 30.06 sign up.
