Domino’s Pizza complaint: Taking cash for payment!

We placed an order for 2 medium pizzas and we went through the drive thru to pick up the order and amount due was $12.97 and I paid with a $20.00 dollar bill and was told that I could not pay with the $20.00 dollar bill that I needed to pay with the exact amount or pay with a credit card, that there is a change shortage. There is no change shortage and I am complaining that we are unable to pay with cash and get change back. Why are you guys trying to go to a cashless society? This is completely insane to do this to people. I understand that the employee was doing what he was told to do. So you people that are in charge need to allow the customers to pay with cash not just credit card and the exact amount. By the way I only had 13.00 dollars to pay and I got 3 cents change back. I really would like for this to be resolved.
Thank you,
A loyal customer
