This guy is not stable. He started texting me at 1230AM (at 2:30AM his time!) that I should book an appointment with him 4 days out, when's not even in my city yet. "I'll see if I can fit you in if you change your mind".
Age-shavers are my pet peeve. What I do with a suspected liar, I ask them what year they were born. As soon as they hesitate or stumble, you know you've caught them.
