Shopkeeper Roger drunk outside clubs (6)
I believe the answer is:
grocer
'shopkeeper' is the definition.
(I've seen this before)
'roger drunk outside clubs' is the wordplay.
'drunk' is an anagram indicator.
'outside' is an insertion indicator.
'clubs' becomes 'c' (abbreviation used in card games such as bridge).
'roger' with letters rearranged gives 'groer'.
'groer' placed around 'c' is 'GROCER'.
(Other definitions for grocer that I've seen before include "Shopkeeper who sells food and household stores" , "Food dealer" , "Provision merchant" , "Merchant who sells foodstuffs" , "Food shop" .)
