The practice of self-serve fountain drinks has now expanded to encompass self-serve sno-cones. People are becoming more accustomed to having their orders customized to their exact preferences and one festival’s Sno-Cone truck made that possible. They provided you with a cup of plain shaved ice but allowed you to do the rest to turn it into a favorite summer treat.
The setup was a win-win for everyone: the truck operator could serve more people and customers were able to mix exotic combinations of flavoring to their liking. It also meant that there was ample syrup to soak through to the bottom of the cup!
When self-serve just is an excuse for customers to do the work of the retailer, there is natural resentment. But when self-serve provides a benefit to the customer as in this case, people are actually pleased to do things themselves. Ask yourself who your “self-serve” is serving: the organization or the customer. Only one causes delight.
