Manager instead of Teller..
Why are these dummies giving the tellers the extra $540.00 she doesn't have the authority to call a maintenance crew?..At least not in any bank I've used.. Any normal half wit would take a complaint of this nature to the bank manager who has the authority to call for a crew to repair the ATM in question...never would a teller have the authority..this is a major flaw in the writing...Of course then the story couldn't proceed as the writer needed it too....But another way could be researched to achieve the same outcome as the teller bolting with the $540.00,
just a thought.
