Selling drinks after last orders (5)
I believe the answer is:
sales
'selling' is the definition.
(thesaurus)
'drinks after last orders' is the wordplay.
'drinks' becomes 'ales' (I've seen this before).
'after' says to put letters next to each other.
'last' indicates one should take the final letters.
The last letter of 'orders' is 's'.
'ales' put after 's' is 'SALES'.
(Other definitions for sales that I've seen before include "Periods when shops offer goods at reduced prices" , "Marketing" , "Business department - retail events" , "Public auctions" , "Occasions for buying at reduced prices" .)
