Waiter trainers claim that an investment in education pays off very quickly for restaurants.
Unlike in Europe, where serving is often a career rather than a backup plan, American table-waiting remains a bootstrap business, and some of the biggest skeptics of waiter training courses and schools are seasoned servers themselves.
In 2008, Milton Sheppard opened the Waiter Training School in the Bronx, N.Y., charging $175 for courses, but the business soon ran out of money. He now operates a clown college in the same space.
