Nicholas G Tiernan. Nicholas G Tiernan is a timewasting cockroach. He will spend HOURS setting up an appointment with you just to cancel the day of over and over again. After weeks of trying, I finally ended up having a session with him. We ****** and when he left I realized he shortchanged me by $60. Totally not worth all the back and forth. I checked his other reviews and he does this to every escort. He even messages several the same day for the same time. Ugh.
