On one occasion, he managed to sneak out from a dinner at the Mansion House for a breath of air with his chum John Betjeman, the well-known poet and snob.

"Napkin rings?" exclaimed the prince, "What on earth are they?"
"Well, sir," explained Betjeman, "There are some people who can't afford fresh linen at every meal, so they shake out their napkins, roll them up, and leave them in those rings to be used again."
"My God!" exclaimed Charles, "Can there be such poverty?"
