One might think that the worst thing that could happen to a web designer is to run out of projects. However, I –like many others – believe that there is something worse than this. If there's someone who can make you regret not having work is the "snake clien"t. Let's look at the etimology:
Snake Client: It is a likable kind of client, he or she is not interest in having a website, a logo, business card or anything else that might be of interest to you. Their sole objective is to cling on to you and talk about their own problems.
