Meituan launched the function of spending first and then paying the bill. Will anyone run away?

I am a merchant of Meituan Hotel. I thought that the quality of the guests now would not be so low. So the cost of the meal was settled when the last guests left the hotel. As a result, some guests really left quietly. I'm also surprised ~ there are five people in the same family. I don't know how such parents educate their children. hey
