In this film (click the picture to run the film - it's in Norwegian but you get the idea), the bank manager arrives and lights the fire (with wood she has chopped herself in the forest).
Then she unlocks the front door, and the safe ("the customers always want money").
They're not actually open yet but someone knocks on the door - but they're just donating some pancakes in case anyone's hungry.
As the customers arrive, they sit and chat and do their knitting while drinking coffee.
The manager knows all their account numbers off by heart so they don't need to worry.
