Worried characters in cafe are dodgy (6)
I believe the answer is:
feared
'worried' is the definition.
(fearing is a kind of worrying)
'characters in cafe are dodgy' is the wordplay.
'characters in' indicates a hidden word.
'FEARED' is hidden within 'cafe are dodgy'.
(Other definitions for feared that I've seen before include "Was in awe of" , "Dreaded" , "Was afraid of" , "Was terrified" , "Was scared of" .)
