Cake and Gosford Park

We were watching Gosford Park on Film 4.
"It must have been such a strange life," I commented, "Your every whim catered for, everyone running round after you, not the smallest thing to worry about - if you were well off, of course."
"A bit like me, you mean?" Keith volunteered.
"Exactly," I said, "You have me to look after your every whim. I reckon I do pretty well, too. At least 9 out of 10. There's just the occasional cake hiatus..."
Keith leaned forward.
"Is that something to do with cake I already ate?" he enquired.
"Possibly," I said.
