It was in Mesopotamia about 3750 years ago, when Nanni was very angry and wrote on his clay tablet in cuneyfom to his supplier Ea-nasir: "What do you think you are to treat someone like me with such contempt? From now on I will not accept any bad copper from you. You will deliver the copper bars to my court in the future, where I will personally select them, and I will return them, for you have treated me with so much contempt. "
