Original Example:
A restaurant had bought the item which is the vanilla powder with supplier. Then they realise that the type of vanilla powder of the supplier is low quality and cannot be used in making the beverege that they want to do. So they want to return the goods, but the supplier tells them that the goods cannot be returned. They trying to change the goods with the supplier, but it was also rejected. So that vanilla powder couldn't be used,and was sealed in the warehouse, and they decide no longer buy any item with the supplier again even the good item or stock that they needed.
Based on Sunk Cost Principles, "Dont cry over split milk", 'Dont throw good money after bad'. The restaurant can use the vanilla powder to reproduce another beverage to the employee, so that the vanilla powder and money wont be waste.
