But then there's the 'really' organized one, as in 'over-organized.  My questionnaire is designed so that unless you mark yes to a question we don't need to deal with it.

I have one client that goes thru & has to comment on every question, even if the answer is no. And if I don't respond to his comments with the finalized return, he wants to 'discuss'.

This client, I meet in the parking lot.  I don't even let him get out of the car.  Nice older man, very lonely tho.  And he pays well.

He does provided source docs (of EVERYTHING) and if the document is more that one page, he staples the pages together. With two tiny staples.  On top of each other.  The ones that are too small for a normal staple puller.
