Anatole is the chef employed by Bertie’s Aunt Dahlia at her country mansion, Brinkley Court. Children from London were evacuated to rural areas during Operation Pied Piper. Bertie wouldn’t have known about the unused morale-boosting propaganda slogan; he has sufficient British stiff-upper-lippedness to come up with the phrase on his own…and, while I’m on the subject, check out these timely userpics.

Dinner:

Walter: Sorry the food is so sparse. Speaking of food, how’s Anatole these days? Is he still managing to be an amazing chef under the rationing?

Bertie: I say, it’s funny you should ask…We’ve got nearly a dozen young evacuees up at Brinkley Court. Chasing them about all day, I find that by dinner I hardly notice what I’m eating.

That is, if the little savages haven’t pillaged the lot already!

Jeeves: I confess, I never imagined you handling children with such serenity.

Bertie: Well, one does what one must. Keep calm and carry on, what?
