Any attempt to look any deeper just leads into more very disturbing sexual thoughts from the pervy old man. All the while, as you harass him with nonsense about fairness, he just casually flips a page through his erotic novel, further adding to the very nauseating thoughts coming off of him. Not at all fazed by your silly complaining, and just waiting for you to offer a counter offer or just agree to the price. Basically put, he is under no obligation to tell you what the full price is, and trying to ween that out of his mind could lead to places where you really do not want to go.
