There are many people who rely on hospitality service jobs to live. Some are careerists, finding a place in a restaurant or catering company that suits their life. Many more become waiters or bartenders while working towards another career or aspiration. Waiting tables, in essence, becomes a waystation, a temporary way to earn money while working toward a dream.

He documented the experience, which was different than he imagined, in his book The Last Supper Club: A Waiter's Requiem.
