Be as defensive as you like guys but the topic of this thread is entitled "Letter from Customer" and the salient point is that the customer was unhappy with wfp!...and so many threads repeat this!
These aren't my words...just what I've read over the years.
Some of you are saying that she's finding excuses to drop her w/c because she can't now afford him! I find that strange as whenever I've been dropped the custy tells me the truth: "Sorry Simon, times are tough and we're cutting back on luxuries"
Perhaps your customers are prouder than mine :

In 4 years I've never been dropped for poor trad work...and I'm mediocre at best

Ian, I'm not anti wfp and indeed can see the earnings potential...but c'mon mate please don't insult my intelligence and tell me that residential customers prefer wfp over trad....your customers may accept it...but do they "prefer" it?
Also when I clean a house for the very 1st time I walk away "knowing" it looks good (in my case "goodish")...I certainly don't have to give the "...they'll look good when I've been a further 2 times" spiel!
And to the wimps who say: "Ooooh!...I'm far too scared to go up ladders"
2 things:
1) Go to the doctors and have a balls implant
or 2
Find a new career!
