I was pleasantly surprised by this book. I was expecting a collection of anecdata, but instead this is a scholarly sociology study of New York's doormen. The author used his students to perform field interviews of doormen to compile a broad portrait of the workers. The interesting takeaways were: (1) Doormen help shape the preferences of tenants, particularly of those who may be new to doormen life. For example, does one prefer food orders brought with or without calling up first. If a tenant isn't explicit about this themselves, doormen ask these questions and get the tenant to take a position. (2) Most doormen don't apply for the job and get it, there are informal relationship networks that get people into the positions, which potentially explains the diversity distribution of the people. (3) Safety is frequently cited as a reason for doormen, but the author could find no reports of there being true safety incidents. This could be ascribed to a concept the author establishes earlier, which is that doormen help project the culture of the building onto the sidewalk and street outside the building. This in turn elevates the status of the neighborhood and improves overall safety. Overall this was an interesting read, but it did get repetitive. It feels like each chapter was written to be independently extractable, because the introduction and conclusions often restate high-level concepts from prior ones.
