I ran into an old acquaintance who wanted me to create a website for him. I've worked with this guy before, years ago, and I didn't want to again. When I refused, he screamed at me. I gave in and said, "I'll do it, if you pay me up front." He said, "Fine", for what it was worth. When I got into the work, he was just as difficult as ever. Nothing I wanted to do was going to make him happy. Therefore, I told him, "Get someone else to help you." He screamed at me again, and I said, "I didn't want to do this in the first place." Then he said, "Then why didn't you tell me?" What a bastard! And by the way, he never paid me up front.
