Chemist is pounds in red needing turnover (9)
I believe the answer is:
dispenser
'chemist' is the definition.
(I've seen this before)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for dispenser that I've seen before include "One filling prescription" , "Container releasing its contents in prescribed amounts" , "one to give out" , "Chemist" , "Pharmacist" .)
