"Casablanca" cafe owner (4)
I believe the answer is:
rick
'casablanca cafe owner' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for rick that I've seen before include "result of making hay?" , "Wrench; haystack" , "Strain neck" , "Haystack; sprain" , "Sprain; hay pile" .)
