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

'a hospitality worker?' is the definition.
'bartender' can be an answer for 'worker?' (bartender is a kind of worker). I am unsure of the 'a hospitality' bit.

'simpson finish with queen' is the wordplay.
'simpson' becomes 'Bart' (Bart Simpson, The Simpsons character).
'finish' becomes 'end' (synonyms).
'with' says to put letters next to each other.
'queen' becomes 'ER' (abbreviation for Elizabeth Regina).
'bart'+'end'+'er'='BARTENDER'

Can you help me to learn more?
