Heh, my Boss and I knock heads on that very issue every week. He thinks he knows everything about my end of the work (website, design, adobe products in general, training the staff, etc. etc.) and I get a big head about his end of the work (show design, fabrication, negotiation, etc. etc.).
Every now and then we have to have a conversation that pretty much goes "I understand that you have expertise in this or that field and I need to learn to respect that. I'm sorry, I'm sure we'll figure out how to work better on the next project"
It just flip flops which one of us is saying it.
