Why do many shops post fake recruitment? In fact, they don't want to recruit people, but post recruitment papers at the door of the store. When someone applies, they will refuse. What's the effect?

There may be the following situations:

First, it has been put in place, but I forgot to tear it off;

Second, some hidden selection conditions are not written on the recruitment paper, such as age, gender, image, speaking and communication skills. At a glance, you can see that unqualified people will directly refuse to apply;

Third, posting recruitment papers is just a propaganda means, mainly to attract the attention of passers-by and then attract customers into the store.
