More people, six? Eight for quota finally? (5)
I believe the answer is:
extra
'more' is the definition.
(I've seen this before)
'people six? eight for quota finally?' is the wordplay.
'finally?' says to take the final letters (I've seen 'finally' mean this).
The last letters of 'people six eight for quota' are 'EXTRA'.
(Other definitions for extra that I've seen before include "appearing in crowd scene" , "More than usual" , "Not a hit certainly" , "Superfluous" , "bit-part player" .)
