Not me, but one of my Players
One of the players in my group will never touch a DM's dice, and will not let the DM touch his dice. Further, he will not let any other player in the group use his dice if, at any time, they have opted to use the DM's dice. Although he brings the largest collection of dice to each session, they can be used only by himself and one other player. The rest of the group have used my dice (I'm the DM) at one time or another, thereby joining his "no touch" list.
