Could pro-waitering serve up some lessons on web scalability? Observing peak hour dining at a New York restaurant gave us some insight.
I was dining at a restaurant the other day with friends. It was a warm and cozy place, nicely decorated with a long, narrow dining room. The food was scrumptious, yet we were getting increasingly frustrated by the service as the night went along.
