It's perfectly correct.Is 'I should be grateful if you would' correct English? I have been working at a firm of accountants for 4 1/2 years now where they use this phrase and when I first came across it I was insistent that it was incorrect as 'should' in this context is a possibility when in fact the context is an obligation.
Most common written example used:
'I should be grateful if you would return the form to me'.
I am happy to stand corrected, but to put my mind at rest I would appreciate any insight anyone has!
