Enter bard, tipsy pub worker (9)
I believe the answer is:
bartender
'pub worker' is the definition.
(I've seen this before)
'enter bard tipsy' is the wordplay.
'tipsy' indicates anagramming the letters.
'enter'+'bard'='enterbard'
'enterbard' anagrammed gives 'BARTENDER'.
(Other definitions for bartender that I've seen before include "One serving" , "local employee" , "server of drinks?" , "Pub employee" , "Liquor salesman" .)
