A lot of clients think the world is a desert island when in fact in reality the world is a crowded bar.
Here's what I mean.
If there are two people on a desert island--one man and one woman, even if one of them is fairly grotesque, chances are sooner or later they're going to copulate.
Of course in a crowded bar where there are lots of options, the result would probably be different.
In the crowded bar scenario you have to do things to stand out and make yourself attractive. You don't have to do that on a desert island.
A lot of agencies and clients don't understand this.
Ergo, ugly work. Or as bad, boring work.
