I worked with a client for several months designing prints for some t-shirts. Having done shirt designs before, I figured it shouldn’t be that difficult. However, I wasn’t given any specs up front on what format they needed from me, which led to this exchange.

Client: He says the EPS files don’t work. He wants it as an AI file.

I sent several AI files. Somehow those ones did not work out either, so I finally explained that I had made shirts with several companies before and had never had a problem. I also threw together this chart, to better illustrate my point:
