Jeweller (Last Minute Shopping)
From Tardis Wiki, the free Doctor Who reference
A jeweller worked in a shop that was visited by Tegan Jovanka one Christmas Eve. He showed her a fob watch that was actually a compass, but couldn't accept some of her money as it was out of circulation since the 1980s. When she didn't have enough to pay for it, he left it on the counter and tended to other customers. (PROSE: Last Minute Shopping)
