Spatter around liquid dispenser (7)
I believe the answer is:
tapster
'liquid dispenser' is the definition.
(archaic term for a person serving drinks)
'spatter around' is the wordplay.
'around' is an anagram indicator.
'spatter' anagrammed gives 'TAPSTER'.
(Other definitions for tapster that I've seen before include "Rat pest (anag.)" , "Bar employee" , "old barman" , "Old barperson" , "Bartender once" .)
