Fire bank employee (7)
I believe the answer is:
cashier
This clue is a double definition.
'fire' is the first definition.
(I've seen this before)
'bank employee' is the second definition.
(someone working in a bank)
(Other definitions for cashier that I've seen before include "One handles the money" , "employee accepting money" , "Fire" , "person taking the money" , "banking officer" .)
