Lousy table setting? Yes, indeed! (10)
I believe the answer is:
absolutely
'yes indeed' is the definition.
(thesaurus)
'lousy table setting?' is the wordplay.
'setting?' is an anagram indicator.
'lousy'+'table'='lousytable'
'lousytable' with letters rearranged gives 'ABSOLUTELY'.
(Other definitions for absolutely that I've seen before include "Dead" , "Totally" , "Utterly" , "Yes, indeed!" , "I wholly agree!" .)
