For mortals, life is awkward. Heels must be rejected after you make your journey mentally (15-minute walk, Central line, change to Victoria line, 10-minute walk, hours standing in queues for drinks and loos) and decide the hobbling isn’t worth it. Chaps would prefer not to wear a cagoule over black tie en-route — a greying flasher’s mac isn’t very Bond — but it’s raining, 10 days till payday and a taxi is unthinkable.
