First, maybe you haven't been engaged in the catering service industry before, such as serving food to guests. You are a freshman who has just entered the business and has no training.

Second, people who may have been instructed or trained by old waiters, but have never learned from others attentively and can't understand the tricks.

Third, I may have been pampered at home since I was a child. I am a person who can't live without someone to take care of me.

Fourth, people who serve customers like serving food may be looked down upon or disliked at an early age. There has always been resistance in my heart, forced by life, and now I have to engage in this industry or similar industries.

Fifth, the last point is the last point, nothing is difficult in the world, nothing is impossible to a willing mind. In other words, nothing is impossible, the key is to look at your heart.
