There is a shoe buyer. They are looking for a waiter. I want to try. What should I say?

First of all, you should know the information of shoes, the brand and material of shoes. When you sell them to customers, you should be able to read their minds, that is, what kind of shoes they want. We should use our own information to express it at the right time, so that customers can feel that this pair of shoes meets their requirements. In a word, promotion is a science, which can't be explained clearly in one or two sentences. If you have time, you can read professional books on this subject.
