      Count cumulative future ordinary bribe payments to this recipient after the answer; smaller payments add together.
      Earlier payments, gifts and ally aid do not count. The sender pays now; the recipient collects the payment at the start of Mentat Pause.
      Payments made during Mentat Pause wait until the start of next turn&apos;s Mentat Pause.
