Bring wife to interview?

Today, Erika and I went to an interview with a potential client for video work in Eatontown, NJ. She waited for me and brought lunch. After I was done she asked me a lot of questions about the interview and encouraged me to pursue video work. She seemed a bit irritated that my supposedly 30-min interview turned into 4 (four!) hours. This brought about an argument on the way back, and rightfully so. The fact that she waited for me kept me be snappy with the client and we got a lot done.
