Is not worried about coming (2,5)
I believe the answer is:
in store
'coming' is the definition.
(I've seen this before)
'is not worried about' is the wordplay.
'worried' indicates anagramming the letters.
'about' becomes 're' (regarding**).
'is'+'not'='isnot'
'isnot' is an anagram of 'insto'.
'insto'+'re'='IN STORE'
(Other definitions for in store that I've seen before include "coming in the future" , "Soon to happen" , "expected to appear" , "coming soon" , "where shoppers are found" .)
