Both Roland's and Eddie's confrontation of the insane AI running the monorail train at the beginning of the book qualify for this. When Blaine demands a riddle from them, Roland only answered with a simple and calm "Fuck you." Blaine becomes enraged as Roland refuses to give him a riddle, scorning him by comparing him to a gadget and how even the lowest beggar or the vilest being was far better than Blaine was.
