So fucking true. Had an offer of 30 - 50 dollars for high quality finished (textured, and next-gen high-poly to low-poly I presume) models recently. Still haven't replied but I think I'll turn it down.
The worst are exactly like the green robot. People who have no idea what processes are involved and starts demanding impossible stuff for very very little money.
I mean... WTF!!! We aren't doing this on Microsoft fucking Word. It took years to learn what we know now. If you knew so many other people who think they know what we know why not make them do what they're asking us to do? And even then, AFTER you've already done everything, he focuses on all the possible flaws he could find no matter how tiny and demands a redo (even if the flaws are a result of his suggestions which you had resisted when still on the concepting stage because you knew it would already look bad).
e.g. "I don't really like the way his horns curve this way... did I suggest that? Impossible! It's all your fault. Now go do 80% of all the work again so I can pay you $10 and be quick about it"
And then there are people who LOVE their own ideas. No matter how idiotic and crappy it is. When dissuading them from that doesn't work I just warn them that it was their idea and I have no responsibility whatsoever if other people wouldn't like the results of my interpretations of his ideas.
e.g. "I want a ninja with a ninja sword and a machine gun driving a tank which is driving through a futuristic city with robot aliens attacking him. I will use it to promote this new caramel candy I'm selling"
And then there are the ones who don't speak much on the initial requirements and then hate everything you turn out.
"What is its purpose? Dimensions? Resolution? Color? Theme?"
...after you've done a few mockups...
"What do you think of this, this, and this?"
...after you've chosen one of your designs at random and presented it:
"WHAT THE HELL IS THIS! This is not what I wanted! Go make another one for the original $10!"
