chinese laundry

A woman sends her clothing out to the Chinese laundry. When it
 came back there were still stains in her panties.
 
The next week she encloses a note to the Chinese laundryman
 that says, "Use more soap on panties."
 
This goes on for several weeks, the woman sending the same note
 to the laundry. "Use more soap on panties."
 
Finally fed up, the Chinese man responded with his own note that
 said," Use more paper on ass."
