Stocktaker taking boss round empty supermarket (7)
I believe the answer is:
rustler
'stocktaker' is the definition.
I can't tell whether this definition defines the answer.
'boss round empty supermarket' is the wordplay.
'boss' becomes 'ruler' (I can't justify this - if you can you should believe this answer much more).
'round' means one lot of letters goes inside another.
'empty' means to remove the middle letters.
'supermarket' with its centre taken out is 'st'.
'ruler' going around 'st' is 'RUSTLER'.
'taking' acts as a link.
Can you help me to learn more?
(Other definitions for rustler that I've seen before include "Cattle-thief" , "lawbreaker" , "Cattle-robber" , "Stealer of livestock" , "Livestock thief" .)
