Bachelor always gets pint (4)
I believe the answer is:
beer
'pint' is the definition.
(I've seen this before)
'bachelor always' is the wordplay.
'bachelor' becomes 'B' (abbreviation e.g. BA=Bachelor of Arts).
'always' becomes 'eer' (poetic way of saying ever).
'b'+'eer'='BEER'
'gets' acts as a link.
(Other definitions for beer that I've seen before include "eg Bitter" , "Perhaps bitter" , "Drink using hops, malt, etc" , "Fermented malt and hops" , "Malt liquor" .)
