Last week, an associate professor at Harvard Business School, where he teaches in the Negotiation, Organizations & Markets unit, ordered what he thought was $53.35 worth of Chinese food from Sichuan Garden’s Brookline Village location. He soon came to the horrifying realization that he had been overcharged. By a total of $4.

If you’ve ever wondered what happens when a Harvard Business School professor thinks a family-run Chinese restaurant screwed him out of $4, you’re about to find out.

At some point in our lives we all have been in the position of either the client or the service provider, or might have faced conflicts, big or small, where values and principles are involved. We are curious though, in the case above, who do you think was right?
