Steak 'n Shake

I took my family to get dinner ordered a shake with mine. Got the wrong shake. Figured since I really wanted the shake I ordered I will say something. Man wrong idea. The manager lady there ripped the milkshake out of my hands almost breaking the entire cup. Calling me a liar. Yelling at me so I said to dump it out and she could see it was made wrong. (She refused) slammed the window shut and walked away talking crap about me. Then gave me a milkshake with finger marks through it. I threw it away. Then I asked for her name so I could call and complain about her, she refused. And told me she’s calling the cops. I told her to go ahead I did nothing wrong and I may even press charges for the way she ripped that shake out of my hands. The cameras in the place can clearly see the way she talked and acted towards a paying customer my order was $30. I have never in my life been treated so poorly by a food place. I honestly couldn’t believe it. Refund, person to be fired, or at least get in trouble how can you employee employees that act like this. I had my kids in the car. And she acted like that. Over a drink that she put her hands in. And thought she was funny. But I had to throw it away. And I lost my entire appetite by the way I was treated. It was a horrible experience and I’m telling everyone that will listen how crappy of a person they have managing their place.
