Cashier (6)
I believe the answer is:
teller
'cashier' is the definition.
(I know that cashier can be written as teller)
This is all the clue.
(Other definitions for teller that I've seen before include "Counter of votes or a bank employee" , "Election official" , "Bank official or reporter" , "one gives relation" , "Bank official to narrate the story" .)
