An interesting way to use variable pricing to allow trade-offs between time and money: “Mary puts up three signs on the side of the truck: $2, $3, and $5. As people come for pizza she asks them to make three lines, one for each sign, based on how much they want to pay. […] The $2 line is long[. …] Some people would rather have pizza sooner than money and wait in the $3 line. […] Mary makes more money, the people who can afford to pay less get cheaper pizza, and the people in a hurry now have an option to trade off time and money.”
