Who might stock lazy Susan (a revolutionary female?) (4)
I believe the answer is:
chef
'who might stock lazy susan' is the definition.
(a lazy Susan is a device for serving food)
'a revolutionary female?' is the wordplay.
'a revolutionary' becomes 'che' (Che Guevara the Marxist revolutionary).
'female?' becomes 'f' (abbreviation).
'che'+'f'='CHEF'
(Other definitions for chef that I've seen before include "member of kitchen staff" , "responsible for courses" , "Chief male cook in restaurant" , "Head cook in a restaurant" , "who has a set of knives?" .)
