A client was upset that the model didn’t meet his expectations, claiming he wanted someone more ethnic.

Me: Do you want me to take another session with a different model? I can arrange an African-american model

Client: No, no, just throw some Photoshop tar on her face and make her black. I don’t want to pay for another session with some African - [here it gets too rude for quoting]

Naturally, I terminated the contract after he finished his racial slurs.
