How much time was spent explaining to the client before you started that your fee is for the amount of work involved, not for the number of pages in the final product?  

Looks like a new client.  How much did they pay last year (if self-employed, at least some of it would be deductible)?  Why were they looking for a new preparer this year?  As if I have to ask.  

If this is the worst client you had this year, you had a good year.
