Teller of tellers? (4,7)
I believe the answer is:
bank manager
'teller' is the definition.
(thesaurus)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for bank manager that I've seen before include "Capt. Mainwaring's civilian job" , "Person once in charge of a Barclays or NatWest branch, say" , "Finance official (to whom one once might have grovelled?)" , "head of branch" , "Head of financial organisation" .)
