Buying milk tea is also a catering business. There are many names for service personnel in the catering industry, which vary from person to person. What do people call waiters, waiters, and what do Beijingers call boys, boys, girls and so on? But if you want people to give you better service, you can call women beautiful and men handsome, which will definitely get more satisfactory service. Of course, if you want to show off in an ostentatious manner, just call the waiter. If you want to pretend to be old, just call "Master, please give me a cup of bamboo charcoal tea XXXXXXXXX". I hope I can inspire you ~ ~ ~
