Accountant queuing here for coffee? (4,7)
I believe the answer is:
bean counter
'accountant' is the definition.
(I know that bean counter is a type of accountant)
I don't understand the remainder of the clue.
(Other definitions for bean counter that I've seen before include "Accountant (slang)" , "Cost-conscious bureaucrat" , "stingy financial official?" , "Accountant, colloquially" , "who worries about finances?" .)
