Came down after ordering nice desk (8)
I believe the answer is:
sickened
'came down' is the definition.
('sicken' can be a synonym of 'come down')
'ordering nice desk' is the wordplay.
'ordering' indicates anagramming the letters.
'nice'+'desk'='nicedesk'
'nicedesk' is an anagram of 'SICKENED'.
'after' is the link.
(Other definitions for sickened that I've seen before include "Disgusted" , "Made ill" , "Nauseated" , "were revolting" .)
