Ice Cream Debt

Create me a game that my friend hands me a bag of chips. My friend will give this to me but with a prize of money that i need to pay. I have 30 seconds to work in an ice cream place and a costumer buys an ice cream for $2 each scoop and i can undo the most recent thing i did. I have to scoop the flavors in order that the costumer ask first is at the bottom and last at the top.
