My sister didn't show her the price list at first when she opened a nail salon in Wanda, and she didn't say anything. She said that it would cost 500 yuan when it was finished, and that it would cost 20 yuan to get a card. Sorry, the nail shop's behavior didn't trigger any laws. You should think about your sister. Why did you go to Wanda for a manicure? Wanda's things are naturally much more expensive than outside, and a bowl of noodles is 50 yuan. Who is to blame for not asking the price before consumption? 2000 is 100, which is a marketing tool. Zhou Yu hit Huang Gai, and one is willing to hit another. I don't have a pit,
