Nine hours later, I was sitting in a spruce office in the Manchester suburb of Wythenshawe, drinking coffee with John “Johnny Brod” Broderick, the man who owned and operated that handsome airport machine. I’d had an idea to try to capture 24 hours in the life of vending machines. These weird, conspicuous objects! With their backs against the wall of everyday existence, they tempt out such a peculiar range of emotions, from relief to frustration, condescension to childish glee. For decades I’d been a steady and unquestioning patron. I figured that by spending some time in the closer company of the machines and their keepers, by immersing myself in their history, by looking to their future, I might get to the bottom of their enduring appeal. What made entrepreneurs from the Victorian age onwards want to hawk their goods in this way? What made generations of us buy? Johnny Brod seemed a good first person to ask.
