He expects to work in a cafe (6)
I believe the answer is:
waiter
'he' is the definition.
'expects to work in a cafe' is the wordplay.
I cannot quite see how this works, but
'work' could be 'wait' (waiting is a kind of working) and 'wait' is found within the answer.
The remaining letters 'er' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for waiter that I've seen before include "Restaurant worker" , "Restaurant staff member" , "Steward" , "Table server" , "Attendant" .)
