We meet Lawrence* by the water; he parks his van opposite a pub that has recently changed hands. He tells me how he would run it differently—he is the kind of person who does things properly. As a Hackney Carriage driver, he feels he has a duty of care towards his customers; it is his job to get them home safely, however long it takes. He has called ambulances for passengers before, sitting and comforting them through illness and intoxication.
