What I would have done. And if they say anything, well, you did submit it. The only thing is they would have had the 2 mails, the original and the rewritten version. So what I would have done, is call him again days later, just to chat and ask some non relevant questions vaguely related to the talk. Is there water if my throat gets dry? How is the crowd? And then I have phone records to back up my story that we had a chat and he approved the first version. You have to make it so you have the answers in advance. If the call was recorded, it was a simple misunderstanding. I'd have argued with him for an hour or longer if I could keep him on the line though, just to annoy him. I really would have. I am that much of an asshole. What did you mean by HAES? How does that related to fatphobia in healthcare? How do I work that into my speech so it suits you? How do you feel about the colour purple? I once did it to a telemarketer and he was pissed I would not buy after all that wasted time, especially after it was well past his shift.
