I was working with a corporation to design a poster for a concert they were having at a local venue. I turned their project around extremely quickly and they seemed pleased. The next day I got an email from the coordinator.
Client: Please alphabetize the lineup.
Which is weird, you should have your headliner on top. But two minutes later I get an email that says:
Client: Nevermind, ignore that."
I pass along the invoice, think everything is great. Two weeks later I get another email.
Client: CAN WE PLEASE HAVE THE UPDATED POSTER!
Me: Which updates are you looking for exactly?
Client: A poster with the alphabetized lineup.
Me: You told me to ignore that email.
Client: That's not what I meant.
