They didn't actually get those damages.

To quote wikipedia:

> In addition, they awarded her $2.7 million in punitive damages. [...] The judge reduced punitive damages to $480,000, three times the compensatory amount, for a total of $640,000. The decision was appealed by both McDonald's and Liebeck in December 1994, but the parties settled out of court for an undisclosed amount.

While I understand the spirit of what you're saying it does the woman a disservice to talk about it as being only spilling a cup of hot coffee. She was severely burned and required substantial medical treatment:

""" Liebeck went into shock and was taken to an emergency room at a hospital. She suffered third-degree burns on six percent of her skin and lesser burns over sixteen percent.[14][13] She remained in the hospital for eight days while she underwent skin grafting. During this period, Liebeck lost 20 pounds (9.1 kg), nearly 20 percent of her body weight, reducing her to 83 pounds (38 kg). After the hospital stay, Liebeck needed care for three weeks, which was provided by her daughter.[15] Liebeck suffered permanent disfigurement after the incident and was partially disabled for two years.[16][17] """
