Heres a little story about one client I had. I had been working with this client getting his site to render how he wanted and other various things. After finishing the rendering problem he stated it didnt render properly in some browsers. The browsers he said I never heard of before. All I know is I got it to render properly in Opera, IE, and Firefox. The big 3 as of what I think. Well after saying to him it was impossible to get a website to render properly in every single browser, he kept insisting it must be done. So I insisted he find someone else to help him. I did not care that he didnt pay me yet. As long as he was out of my hair.
