Rudely treat us as soaks (9)

I believe the answer is:

saturates

'soaks' is the definition.
('saturate' can be a synonym of 'soak')

'rudely treat us as' is the wordplay.
'rudely' is an anagram indicator.
'treat'+'us'+'as'='treatusas'
'treatusas' is an anagram of 'SATURATES'.

(Other definitions for saturates that I've seen before include "floods" , "Soaks" .)

I've seen this clue in The Independent and The Telegraph.
