Kyoto Japanese Steak House

The customer came into the business on Wednesday evening, August 30, 2017. She ordered the early bird steak and a side of chicken coated with garlic butter. I prepared all her food with garlic butter as requested. She took it out and came back in approximately 15-minutes
later. The food had already been mixed up and eaten. She complained that I did not coat with garlic butter and there was no garlic taste. She argued that I did not, I said I did. I told her that I would add more garlic, so I did and then she complained that she did not like the food and wanted her money back. I told her the best I can do is redo the half portion of food that was left since she had already eaten half of it. She said no and that she wanted her money back, and I told her I could not because she already ate the food and nothing was wrong with it except that she complained there was no garlic taste. She demanded her money back again and started yelling and cussing at me. I told her to please not cuss at me and then she said she would file a complaint and left
