One of the best sessions I went to at Bar Camp Canberra 2011 was “How to Handle Difficult Clients” by Danni (@daniib) and Jason (@jhando).
I found them both to be engaging speakers although it was mostly a conversation. Which gave me some insight into what it might be like to be a client ish.
BTW I thought the session was great and some other folks spoke to me about it later and Lurved it too
