From first thought to knock, on a real clock
Take an ordinary Thursday. At twenty to nine a reader finishes dinner near Spui and walks back toward his hotel, already fairly sure of what he wants from the rest of the night. At a quarter to nine he types four lines into WhatsApp. By five to nine the reply has named Patricia, who sets out from beside the Dam, and given a window of twenty to thirty minutes.
He has time to take the lift, turn the room heating up, clear his jacket off the bed and switch on one lamp. At nineteen minutes past, she knocks. Nothing in that sequence required foresight, a deposit or a phone call, and nothing in it was hurried either. That is the whole promise of a same-evening booking, and the rest of this page simply explains how each of those minutes is protected.
