Subway complaint: bad service to Spanish people

on December 13, 2023, my wife and I went to Walmart to get some groceries and after finishing we stop to eat in subway, and I saw how Michael the person in charge of serving the food was serving my food with attitude and told my wife in bad way to get out of subway with the shopping cart. things that if she asks in good way is ok but she did not. when I went to pay, I have 100 Dolar bill and one again with attitude did not want to give me the food because she can’t accept,100 dollars bill I ask for her supervisor and her supervisor was with attitude also.at this point two ladies told me they were threated bad because she doesn’t know Inglish .is when I realize that was more of race problem at subway inside of Walmart subway supervisor was Kim and the person serving food was Michael
