Indignation seeing cleaner at home pocketing grand (7)
I believe the answer is:
chagrin
'indignation' is the definition.
'cleaner at home pocketing grand' is the wordplay.
'cleaner' becomes 'char' (charwoman is a type of cleaner).
'at home' becomes 'in' ('in' can be similar in meaning to 'at home').
'pocketing' means one lot of letters goes inside another.
'grand' becomes 'g' ('G' can be a synonym of 'grand').
'char'+'in'='charin'
'charin' enclosing 'g' is 'CHAGRIN'.
'seeing' is the link.
(Other definitions for chagrin that I've seen before include "Annoyance/shame at one's failure" , "Feeling of vexation or embarrassment" , "Strong feeling of embarrassment" , "Feeling of annoyance and embarrassment" , "Arching with annoyed disappointment" .)
