My husband and I have ordered 2 regular lemonades, 2 shack burgers, and a side of fries. When we started eating, we realized there were no tomatoes on the sandwiches. I politely went back and told the lady at the desk. Surprisingly, the answer was: "we have no tomatoes". I said it was wrong because I had bought a sandwich with tomatoes and nobody told me that the ingredient was missing. She started being aggressive and told me there was nothing she could do about it, they were about to close and the tomatoes were over. At that point, all the other employees joined her and started yelling and being aggressive toward us. I told them I had paid for a sandwich with tomatoes and wanted my money back. That is when she gave us an incredible answer: YOU DID NOT PAY FOR THE TOMATOES, YOU HAVE PAID FOR THE BURGER (??????). They said aggressively that if we really wanted tomatoes, she could go to the other store (far away at the airport) to get some. Of course, we refused that terrible idea. We were shocked with this attitude and asked them for their names. They refused to show their badges and to tell their names and even asked what were OUR NAMES. One of them told us her name was Ashly (but we can't really know if it is true). One of the ladies was so aggressive that her colleague had to hold her. We gave up and went away very angry and upset. 5 minutes later, an old man came to our table and said he had witnessed everything and that he was shocked about the ladies' behavior. We have never witnessed something like that and we have never been so mistreated in a restaurant. We were very surprised about the lack of customer service. They should have stopped selling the sandwich if there were no appropriate ingredients OR should have informed us before we order. They did none of this. We have paid for something we did not receive and they tried to make us look wrong for it. Unbelievable.
