What is the meaning of "male public relations" in Korean drama "Please Miss"?

It is hotel management. I can tell you clearly that the unspoken rule is: you can ensure your health, you can get some "on-the-job training", you can ensure that you wear top-grade packaging, and your salary is considerable, but only if you ensure the satisfaction of your guests, try your best to meet all their requirements and provide the best service, even if it is unreasonable. To put it bluntly, it is to satisfy some women who are psychologically empty and abnormal, which is what people call ducks!
