Great (but clueless) client. I went to a meeting with the client to discuss a way forward for his website revamp. First off he showed me his idea, which was a visual of the Windows desktop, with folders for different sections of the website, click on a folder and it opens revealing the different website pages. It went on basically describing how windows works. When he'd finished I said, with a cheeky smile, "that must be one of the fucking shityest ideas I've ever heard". We both started laughing.
