Why eat in resort? It's preventing progress (2,3,3)
I believe the answer is:
in the way
'preventing progress' is the definition.
(I've seen this in another clue)
'why eat in resort?' is the wordplay.
'resort?' indicates an anagram (re-sort the letters).
'why'+'eat'+'in'='whyeatin'
'whyeatin' anagrammed gives 'IN THE WAY'.
'it's' is the link.
(Other definitions for in the way that I've seen before include "Causing obstruction" , "Obstructing" , "causing a blockage" , "Being . . . . . . . . like 11 Across" , "Impeding one's progress" .)
