Poul Anderson's hero, Dominic Flandry:
"...went to Terra on leave, was invited to the perpetual banquet of the Lyonid family, spent three epochal months..." (
Flandry Of Terra, London, 1976, p. 9).
A perpetual banquet, like the Mad Tea Party in
Alice? How would that work? Domestic slaves serve the family and guests who are seated at one half of a large circular table while a second team of slaves clears and resets the other half so that the banqueters can keep moving around the table? (I say "slaves" because we are talking about the Terran Empire here. Otherwise, domestic servants would play this role.)
Assuming eight hours for sleep, no one can possibly eat continuously for sixteen hours every day indefinitely. The family must take it in turns to host the meal while the guests change every three months or so. There must also be intervals, as at the theatre, when guests can attend to other business using computer consoles either set in the table or just behind where they sit or can stretch their legs by strolling around the Lyonid mansion and garden.
Tolkien's Hobbits eat seven meals a day, I think. If these were spaced out through the day, they might just provide enough instalments for a perpetual banquet.
8.00: rise, butler brings cup of tea.
9.00-10.00: breakfast.
10.00-11.00: second breakfast.
11.00-12.00: elevenses.
12.00-14.00: lunch.
14.00-16.00: buffet snacks available from tables set around the dining hall walls.
16.00-17.00: afternoon tea.
17.00-18.00: buffet snacks as above.
18.00-20.00: dinner.
20.00-22.00: buffet snacks available in the bar.
22.00-23.30: supper.
24.00: retire.
By eating and drinking sparingly while concentrating on enjoying the conversation and no doubt also entertainment provided, a guest might survive for a few months, as Flandry does.
