Bus conductor (The Chase)
From Tardis Wiki, the free Doctor Who reference
A bus conductor conducted bus's in London sometime in 1965. When Ian Chesterton and Barbara Wright returned to London, they rode on his bus. When Ian asked for two three's, the conductor thought he was joking, and asked them if they had been on the moon. Ian then told him no, but he was getting warm. (TV: "The Planet of Decision")
