A fanciful repurposed illustration by Edward Gorey of Mr. Earbrass (from "The Unstrung Harp") reclining on a chaise and having tea. Text has been added beneath the illustration in a Gorey-esque font that reads "Wheeler worried that the tea would vanish into the black hole and take its entropy with it, thereby decreasing the total entropy of the universe."

Bekenstein was motivated by discussions with his advisor John Wheeler, who was worried about what would happen to the entropy of a hot cup of tea poured into a black hole.
Would the entropy associated with the tea vanish like everything else? That would seem to contradict the second law of thermodynamics, which would have profound implications for our understanding of physics.
