(I was working at the paint desk when a customer calls the store.)

Customer: “Can you mix up my paint and have it ready when I get there? I have the formula.”

Me: “I can take the formula and stage it, but I can’t mix it until you arrive. What is the formula on the can?”

Customer: “It’s got 20% Magenta, 30% Cyan, 30% Yellow Oxide, and 30% White.”

Me: “It says that on the can?”

Customer: “No, that’s what I had them put in last time.”

Me: “Sir, that’s more than 100%. The formula you gave me is impossible to make.”

Customer: “I’ll just come down there and have someone who understands make it for me.” *click*
