Dismiss teller (7)

I believe the answer is:

cashier

I believe this clue is a double definition.

'dismiss' is the first definition.
(thesaurus)

'teller' is the second definition.
('cashier' can be a synonym of 'teller')

(Other definitions for cashier that I've seen before include "take out of service" , "Money handler; dismiss from the forces" , "Bank worker - dismiss from the armed forces" , "Dismiss (someone) from the armed forces in disgrace" , "person dealing in LSD, say, once?" .)

I've seen this clue in The Telegraph and The Guardian.
