A very amusing site with brief stories/conversations about "problem clients." Most are sent in by designers, but they're things photographers can definitely relate to: http://clientsfromhell.net An example: "Client: I don’t like the way you’ve placed those two trees! Me: OK, where would you like them instead? Client: I don’t know, I just don’t like them that way. Can you not put them in a line like that? Me: You… don’t want these two trees to be in a line? Client: Right. Don’t put them in a line. Me: Should I put them in a circle instead? Client: Yes! That would be much better!"
