Since the 1980s, with the development of social economy, people's living standards continue to improve, the pace of life continues to accelerate, the restaurant industry has been unprecedented prosperity. The cost of using public **** chopsticks is relatively low, only need to spend the cost of purchasing chopsticks and sterilizer. Generally speaking, operators don't pay much attention to the cleanliness of public **** chopsticks, especially during the peak of the dining season, they just simply rinse them, and they are not sterilized, so the public **** chopsticks are generally not very hygienic. You can analyze the 3 forms of chopsticks: disposable chopsticks, public **** chopsticks, and complete sets of tableware. You can analyze consumers' consumption habits, the cost of various chopsticks, the interests of merchants, etc. I guess you can deal with this debate if you write it that way! I can think of so much, I hope it can help you!
