Get rid of accountant? (7)
I believe the answer is:
cashier
I believe this clue is a double definition.
'get rid of' is the first definition.
(cashiering is a kind of getting rid of)
'accountant?' is the second definition.
(thesaurus)
(Other definitions for cashier that I've seen before include "Sack" , "Dismiss; receiver and payer of money" , "person taking the money" , "take out of service" , "Discharge" .)
