At the start of a website project:

Me: If you have your own design in mind that you can give to me, the project will cost (x). But if you want to start from scratch, you’ll need to pay (2x) for me to bring in a designer.

She stated that they have no idea about what kind of design they wanted, and paid me the extra to get a designer. Two months later and over 200 hours of work on the site, the site was ready to go live the next day (the deadline). Then…

Client: I’ve attached the design we want to go with, if you could just make that happen that would be great! Thanks! :)

Attached was a 200mb PDF.

I would chalk it up to an error in communication, if she hadn’t sat through 5 design meetings with the designer and I, hammering out details.
