Pub employee showing skill when interrupting binge (9)
I believe the answer is:
'pub employee' is the definition.
(I've seen this before)
'skill when interrupting binge' is the wordplay.
'skill' becomes 'art' (both can mean a talent).
'when interrupting' indicates putting letters inside.
'binge' becomes 'bender' (synonyms).
'art' going inside 'bender' is 'BARTENDER'.
'showing' is the link.
(Other definitions for bartender that I've seen before include "source of 9 [ROUND] ?" , "Pub employee" , "Landlord perhaps" , "Pub worker" , "local employee" .)
