I had a really bad experience at McDonald's today. First of all, the meal they prepared for me was not the meal I ordered. I asked them to prepare again, and they did so without even apologizing. The second meal was still two sundaes short! I asked them to check the order again for the second time. Please give me the sundae. The result prepares the young lady to ignore me, the little elder brother that orders a dining table only comes to ask what I need. He gave me sundaes, but they were only two thirds the size I'd ever seen! I've been completely disappointed. I placed an order on my mobile APP, specifying the types and number of sauces I needed. They didn't have everything ready. It's too much to ask me what sauce I need and still not have it ready. I feel badly treated! They didn't have napkins, straws, ketchup for French fries or the sauce I asked for. When I finally got home and began to eat, I found that instead of coke, I had Pepper in my hand. I was finally angry! This is definitely the worst restaurant experience I've had in a long time in America! What happened to McDonald's? This is not the first time for me to visit this restaurant. In the past, the McDonald's staff served me very well and warmly. Today, the staff are indifferent and impatient, and even the service is often wrong. I hope you can receive my feedback. I don't think I want to visit this store again for the next few months.
