Why do shopping malls need warm tips?

This is a means of public-private relationship, which I think mainly reflects the quality and all-round service of the shopping mall itself.

This kind of service is not only a superficial service for customers' shopping, but also a service for customers' mood and safety. In fact, it is also the improvement of people's spiritual connotation and civilization, just as people can't buy a house just to live, but also to buy a sense of belonging and security; People can't just buy clothes to keep out the cold, but buy confidence and image; Even when buying funeral supplies after death, we will not forget to buy imaginary life in another world at the same time.
