Why do some people have to be so self-centered?

They asked for my help with a logo. I said I will help even without any charges. I know they don't want to spend money. And that's why I frankly said I can help free. But then they said they will feel bad then and ask for my quotation. Ok, I sent.

They said "Sorry it is too high, can you give 60% discount?" Ok, sure.

Then they asked if they can get it in 4 days. Ok, I said.

Then they said they changed the name just now.

At least give me a fucking ounce of respect.
