After fuss, difficult dismissing hotel's sommelier, perhaps (7)

Ross

I believe the answer is:

steward

I'm a little stuck... Click here to teach me more about this clue!

'sommelier perhaps' is the definition.
I can't tell whether this definition defines the answer.

'after fuss difficult dismissing hotel's' is the wordplay.
'after fuss' becomes 'stew' (I've seen this in another clue. I am not sure about the 'after' bit.).
'difficult' becomes 'hard' (associated in meaning).
'dismissing' suggests deleting specific letters.
'hotel' becomes 'h' (phonetic alphabet: alpha, bravo, charlie etc.).
'hard' with 'h' removed is 'ard'.
'stew'+'ard'='STEWARD'

Can you help me to learn more?

(Other definitions for steward that I've seen before include "Crew member" , "Superintendent" , "Caretaker" , "Attendant on ship - race official" , "Horse-racing official" .)
