The change of the proportion of male and female customers in the takeout industry is mainly related to the development of the takeout industry. At first, the number of female customers in the takeout industry was larger than that of male customers, which was mainly related to the natural differences between men and women. First, generally speaking, women are not active, while men are the opposite. Then, women are more likely to be greedy for small and cheap things, while red envelopes are often used for takeout, which men don't care much about. However, with the further improvement of the takeout service system, more and more businesses have joined in this field, attracting a large number of men. On the other hand, men's increasing work pressure makes them more willing to save time by ordering takeout food. Therefore, the number of male customers increased steadily, and finally the proportion of female customers was roughly the same between 2017 and 2019.
