Wobbly flab in store where one's fed breakfast and evening meal (4,5)
I believe the answer is:
half board
'where one's fed breakfast and evening meal' is the definition.
(provision available at some hotels)
'wobbly flab in store' is the wordplay.
'wobbly' indicates an anagram (I've seen this in other clues).
'in' is an insertion indicator.
'store' becomes 'hoard' (hoard is a kind of store).
'flab' with letters rearranged gives 'alfb'.
'alfb' placed inside 'hoard' is 'HALF-BOARD'.
(Other definitions for half board that I've seen before include "Dinner, bed and breakfast" , "Bed, breakfast and evening meal" , "Bed, breakfast and one main meal" , "pension arrangement" , "hotel regime" .)
