Domino’s Pizza complaint: inefficient staff member

I’ve just had a really bad experience with one of the staff at the Dominoes located on 34th Street South in St Petersburg, Florida that I’d like to bring to someone’s attention please.
After having placed an order online and then driving to the Dominoes location to pick it up I was told immediately that it wasn’t ready because she was the “only one there”. At the same time there was another customer in the store who was told that he’d have to wait at least ½ hour because she is so backed up. At this point it became obvious that she was in NO HURRY at all to even get started. When I said to her that maybe she could get the order started, she became obnoxious and proceeded to lecture me about being the only one there. Again rather than getting the order started, she chose instead to confront me rather than just getting it done.
She then started throwing things around which I again remarked on which unfortunately gave her another reason to stop what she was doing and then she ly cancelled my order.
I told her I wanted to speak to the manager, she said she is the manager, so I asked for the owner’s name and phone number which she refused to give me and then told me to leave the store. I asked again for the owners contact info when a man came out from the back and told me to leave and threatened to call the police if I didn’t leave. This was overall a most unnecessarily rude and awful experience. This store is in desperate need of customer service training. In no way at all did I deserve to be treated like that! If staff can’t show that they are at least trying to get caught up why should anyone have sympathy? I have been in customer service for many years and this type of treatment and behavior would have had anyone fired in a heartbeat.
