I dont know what kind of area you are in and what the wc is like, but i would think its fairly safe to say that for a wc to go to the trouble of washing her windows with dirt he has been ripped off - if he was lieing, he wouldnt of taken it so bad - just gone and conned someone else, the woman sounds like trouble If you take the job price high and make sure she pays whilst you are there or before you commence cleaning!
