This was, sadly, before I started using contracts and worked on a less structured level with friends.
A friend contacted me with a request.
Client: Hey, I need a new logo, are you available?
Me: Hey, remember when I did your last logo to your specifications and you declined to pay for it because you didn't wind up using it?
Client: What's the problem? We didn't use it!
Me: Look. If you want a new logo, I'll do it, but the catch is that you pay for it.
Me: Even if you don't use it.
Client: Yes, yes, fine!
I do the new logo, to his specifications, and he doesn't wind up using it.
Me: All right, whatever, that'll be $$$ please.
Client: Why should I pay for a logo I'm not going to use?
