For example, there are I’ve seen door-to-door service customers who don’t want to serve when they see a greasy kitchen or a smelly toilet. There are also people who leave before the service is completed. There are also people who take away the customer’s belongings after the service is over. Of course, , can also refer to various cleaning staff who appear in prank or funny forms.
However, such cleaners must account for less than 1%, otherwise, the housekeeping industry would have closed down long ago!
