In college I worked as a waitress for 10 hour shifts with 8-10 tables at a time, and it was madness. (Mario Batali was a cook when I was there). And I remember thinking all the waitresses and cooks were just really fast and upbeat, the way I was. And then my boyfriend at the time, also a cook, laughed at my ignorance and told me that almost everyone else was doing coke or crank all night long. I had no idea.
