Can unmanned vending machines for adult products really make money?

I don't have to worry about the market. I'm not saying that when unmanned sales first came out a few years ago, many customers were worried about the sales and demand in the market and worried that they could not do it. However, in recent years, such stores can be seen everywhere in every city, county and town, which proves the market demand and adult products are also included in the department store series. In this case, opening a store will only earn more and earn less, and all the benefits are still considerable.
