First of all, the cost of doing a pedicure shop is much lower than that of other service industries. In daily service industries, such as catering and housekeeping, it takes months or even more than a year to complete a set of standard processes. Other shops and waiters also spend a lot of money. My family is engaged in catering. Although the storefront is not big, the annual cost is around several hundred thousand, which is basically hard money. But pedicure shops are different. First of all, pedicure shops are generally small, because they don't need catering and other services. So there are not so many complications. Basically, a room of 10 square meters is enough to open a shop, and there is no need for too many people to run the shop at will. Therefore, opening a pedicure shop every year can save a lot of money.
Secondly, the pedicure shop clerk is a good move and the cost is low. As far as my current city is concerned, it is often seen that many shops are recruiting pedicure clerks, because pedicure is not a massage in the strict sense, and clerks do not need to obtain qualifications through formal medical study. As long as after a period of training, basically many shop assistants can work smoothly, which has caused some chaos in pedicure shops at present, that is, shops are opened everywhere and personnel are easy to recruit. Many shopkeepers don't pay their clerks very high wages, and most of the costs of violence can be borne by themselves. I personally have done several foot massages, and to be honest, the level of each family is really different. Some of them can clearly see the rigidity of technology, as if they had just learned it, from which we can see how violent the price is.
Finally, some additional services of pedicure shops are very profiteering. Ordinary pedicure costs tens of dollars at a time, which is acceptable. But now many pedicure shops will charge hundreds of dollars more for adding some red wine or milk to their foot baths, and the cost of these things is often only a dozen dollars. There are many such additional services, and some people will experience them when there is a market, so pedicure shops are relatively profiteering industries.
