Checkers & Rally's

On August 11, 2020 I pulled into the Checkers on East Locust street In Davenport, IA. I order a cheeseburger and a medium ice tea. I handed the cashier a $20 bill and she returned to me a hand full of change. She reported that I only gave her a $5 bill. The manger, named Tamera came out and was very rude and preceded to scream and yell at me. I've never been treated so rudely as a customer in my life! Someone who treats customers like this should NOT be in a position of management. I'd really appreciate this issue to be resolved. Not only was I treated poorly, I ended up paying $20 for a cheeseburger and medium ice tea!
