An elderly gentleman came to us to put together a mail-out for his non-profit organization. He gave us the mailing lists, about 4,000 addresses in total. He also gave us the file he wanted us to print and mail: a PowerPoint slideshow.

Obviously, we took the contents of that slideshow and recreated it as a flyer rather than sending out a PowerPoint print-out. We sent him proofs asking for feedback beforehand but he said he was “sure it would be fine.”

It wasn’t fine.

Client: Why didn’t you send what I gave you?

Me: PowerPoint isn’t a design program, and it isn’t appropriate for printing. We tried to recreate what you gave us as a PDF in the proper dimensions.

Client: I don’t understand. Next time, just do what I tell you.
