Excellent, London.

I recall a scene from Hercule Poirot in which he paces up and down, hesitating about boarding a ship (which he hates because of his proneness to seasickness). The impatient and agitated Commander asks Hastings what Poirot is doing.

"He's thinking," replies Hastings.

"We DON'T PAY HIM TO THINK!" Shouted the Commander.

(Agatha Christie)

Best.
