Would salesman tip a storekeeper for displaying first course. . . (9)

I believe the answer is:

antipasto

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

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

'would salesman tip a storekeeper for' is the wordplay.
'ANTIPASTO' is hidden within the letters.
But, I am uncertain how this is indicated.

'displaying' is the link.

Can you help me to learn more?

(Other definitions for antipasto that I've seen before include "Italian appetisers" , "Italian appetiser" , "Appetizer course in an Italian meal" , "Italian dish" , "Italian hors d'oeuvre" .)

I've seen this clue in the Sydney Morning Herald.
