The sheer, utter irony of this is the "ginormous" amount of firepower they (or any bank) has at its cash vaults...you know, the kind where they drive pallets of $$,$$$,$$$ around with forklifts, shotguns on the wall, all employees open carrying, etc...got a buddy who works on cash count machines at these non-descript locations...he always gets followed around by an armed escort. The other day I was giving him a hard time because he never carries cash...he said "in my business it's highly discouraged...if you have no cash on you/in your wallet, you have an easier time should you get accused of fingering some money."
No reason to show it to anyone else unless it's a situation of last resort but even then, it's really no one else's business.
