Discharge treasurer? (7)
I believe the answer is:
cashier
I believe this clue is a double definition.
'discharge' is the first definition.
(cashiering is a kind of discharging)
'treasurer?' is the second definition.
(thesaurus)
(Other definitions for cashier that I've seen before include "person taking the money" , "banking officer" , "Teller - dismiss in disgrace" , "Bank employee" , "Employee who takes in or gives out money" .)
