Me: The event is this weekend and you still haven’t sent me high res graphics for the poster.
Client: But you took a picture of last year’s poster. Can’t you just use that?
Me: No. That was just for my reference for layout.
Client: (2 days later) I’m going to have to bail, I can’t get you what you want in time. I’ve found another solution.
Me: (same day, later) That image you posted on Facebook? You’re going to have to take it down. It has copyright statements all over it, which means you cannot use it without paying for it.
