Hotel gets irritated about entourage (7-2)

I believe the answer is:

hangers-on

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

'entourage' is the definition.
(I've seen this before)

'hotel gets irritated about' is the wordplay.
'hotel' becomes 'h' (phonetic alphabet).
'gets irritated' becomes 'angers' (I can't justify this - if you can you should give a lot more credence to this answer).
'about' becomes 'on' (as in a book 'on' a certain topic).
'h'+'angers'+'on'='HANGERS-ON'

Can you help me to learn more?

(Other definitions for hangers-on that I've seen before include "Persistent (and annoying) companions" , "Sycophants, unwanted followers" , "Minions" , "Sycophantic associates" , "Sycophantic followers - dependants" .)
