Whataburger complaint: Store manager being hostile

Drove through the drive through at round rock whataburger and manager was super rude to me cussed me out and was very hostile. My daughter and i were very terrified through the experience. He kept reaching out the window cussing me out telling me to get the fk out of here. He seemed to have lashed out due to a bad day or something. However that is no excuse to treat someone that way. I Had to call the round rock police and still got over charged for my order, his opinion of my ordered should have not caused such an issue. The expectations of a store manager should not include violence. Highly disappointed on the way we were treated today. The entire staff seemed to encourage his wild behavior. I see why they didn’t know how to handle the situation any better. I have worked for whataburger in my past and treating our customers in that manner is beyond unacceptable.
