Kindness occasionally may get you a date in Rome (4)
I believe the answer is:
ides
'a date in rome' is the definition.
(Roman calendar term, as in the Ides of March)
'kindness occasionally' is the wordplay.
'occasionally' means one should take alternating letters.
The alternating letters of 'kindness' are 'IDES'.
'may get you' is the link.
(Other definitions for ides that I've seen before include "Caesar was warned to beware the ones of March" , "March day Caesar died" , "Roman calendar day roughly in the middle of the month" , "Unlucky day for Julius Caesar" , "Caesar's fateful day" .)
