Crossword Genius

A lot of rudeness shocked consumer, finally (3-4)

Ross

I believe the answer is:

end-user

'consumer finally' is the definition.
(final user of a product)

'a lot of rudeness shocked' is the wordplay.
'a lot of' means to remove the last letter (I've seen 'lots of' mean this (the majority of the word)).
'shocked' indicates an anagram (letters are shocked or disrupted).
'rudeness' with its last letter taken off is 'rudenes'.
'rudenes' anagrammed gives 'END-USER'.

I've seen this clue in The Guardian.
