Who follows which driver, who must not be seated next to whom, which CEO will only come if a particular team principal is in the box, who is being courted by a competitor's box at the same fixture, who proposed in the paddock last year, who is uninterested in motor racing but loves the Friday lunch. Every invitation, every box, every paddock walk turns on detail that lives in hosts' heads, on plus-one lists pasted into emails and in WhatsApp messages between account managers. When they move on, transfer or take a sabbatical, the firm cannot reach the intelligence that wins the next account. So VIPs feel forgotten, new hosts start from zero, and accounts that took decades to build leak away one resignation at a time.
