I had scheduled an appt with him when he was visiting town a while back. He could only do outcalls, which was not ideal for me, but I jumped through some hoops to arrange a time to make that happen. Up until that point, communicating with him had been friendly and prompt, and we had exchanged a number of texts due to the difficulty of arranging an outcall. Then, a couple hours before our afternoon appointment, I texted to reconfirm. No answer. I texted again at the appointment time. No answer. Finally, about 2 hours after our appointment time, I got a response. He said he didn't realize how bad the traffic would be (which I can believe) and that he ended up skipping my appointment so that he could make the next appointment. Of course, he didn't notify me of that until well past our appointment. If what he's saying is true, he knew he was going to miss my appointment, but did not make an effort to let me know until 2 hours afterwards.
Anyways, that's my 2 cents!
