David Thorne to his least-favorite client:

Disregarding the fact that you have still not paid me for work I completed earlier this year despite several assertions that you would do so, I would be delighted to spend my free time creating logos and pie charts for you based on further vague promises of future possible payment. Please find attached pie chart as requested and let me know of any changes required.

And that’s just the beginning. This is par for the course when you’re having designers do work for you on spec.
