Late, pushy, disrespectful
The person who was supposed to give me the presentation was over 15 minutes late for the call. Then proceeded to talk down to me when I said I could still talk but wouldn't be able to take notes or anything because I was driving. He asked for my credit card information at the end. I told him I was still driving. He became pushy. I told him I would respond to him the next day. When I let him know I decided to go in a different direction, he emailed me back and insulted me. NEVER AGAIN!
