Archie was worried, and no wonder. He was in London for a flight to South Africa, but he’d left his passport in Edinburgh. With his plane due to leave at 9pm that night, he’d need his passport by 7.45 at the absolute latest. So could we send a same day passport courier to pick up his passport and deliver it from Edinburgh to London within that time, including contending with the Friday night rush hour? If we couldn’t, Archie would have pay out for an expensive night in a hotel, kick his heels in London for another 24 hours, and wait for the next flight home.
