What problems do tea artists usually encounter in their work?

Poor quality guests, tricky guests, generally doubt the quality of tea (some people say that even if the tea is not good, good tea-making technology will make the tea taste good), and occasionally ask about tea knowledge. Guests who know will generally speak for themselves, and those who don't will ask themselves and organize their own language. But I've only been a tea artist for a few months, and I'm usually an acquaintance of the boss, a friend of a friend, and a friend of a friend. In fact, there are few difficult problems. Do your job well, smile at others and listen to the opinions of guests patiently. No big problem. If you have problems that you can't handle, just find an excuse to go out to the private room and find a leader to solve them.

That's all. I haven't done it for a long time. I wonder if I can help you.
