About 15 years ago I was contracted to design a business card for a client. The front of the card was to be a full-sized image of him holding his briefcase. These were the early days of digital cameras and the picture he sent was not great quality. I asked for another photo but he said to go ahead with what I had so I created the card to his specs.
Client: Hey, the card looks great but I have a question. Is there a reason why my eyes are closed?
Me: Yes. There is.
Client: Oh really? Why is that now?
Me: Because when you took the picture, your eyes were closed.
He hung up on me and never called me again.
