Thanks for sharing the above. I am now going to give up. I had a very similar experience. Meeting was set. He then sends a text that i never sent him a pic. I responded that he never asked. He then apologized and said he mixed me up with someone else. So I assumed we were all good. I was walking to his hotel in NYC. Got a text "Can we do later"? Since my time was tight, I could not.
He has the right to ask for a pic. However, essentially cancelling on me 10 minutes beforehand is unacceptable.
