Client: I don’t like the T-shirt design. I’m going to want my money back.

Me: Why?

Client: The logo turned out black

Me: Well, yeah - that’s what you asked for. 

Client: It doesn’t show up on a black T-shirt.

Me: You said it was going to be printed on a white or coloured T-shirt.

Client: But the black T-shirts were cheaper…

Me: I’m sorry, but I was pretty clear you needed to print on a coloured or white shirt. 

Client: Yeah, I remember now. But to afford ordering more T-shirts, we have to cancel your payment nontheless.
