A Great Business Lesson
The donut guy that lets you make your own change. This is a beautiful business design principle. I imagine most folks feel that the trust is so unusual, that it's really beneath them to try and jip this guy for small change. But more valuably, if you treat your customers as adults, they'll behave like adults. This is something JetBlue and SouthWest have known for a long time, and the major air carriers won't learn even unto bankruptcy.
