Diana's a girl cashier (7)

Ross

I believe the answer is:

dismiss

'cashier' is the definition.
(I've seen this before)

'diana's a girl' is the wordplay.
'diana's' becomes 'Di's' (Di is short for Diana).
'a girl' becomes 'miss' (term of address for an unmarried woman).
'dis'+'miss'='DISMISS'

(Other definitions for dismiss that I've seen before include "Remove from office" , "Sack - send away" , "Reject, send away" , "military order" , "Drop" .)

I've seen this clue in The Globe and Mail.
