I wouldn't dream of asking my customers what they think!
That has the potential to open a whole can of worms!!
Where WFP is concerned, safety wasn't top of my list of reasons for changing over, niether was the potential to earn more money.
I was on the point of jacking it all in after 20 years of window cleaning, working off ladders was becoming increasingly hard, looking at the future I knew I would not be able to afford to retire, so I needed to find a way that would allow me to well extend my working life, no way on this earth would I want to be climbing 35ft up a ladder at 65+
So for me that was my motivation for changing.
I will occasionally use the health & safety angle on a customer, I quite bluntly refuse to work off a ladder (except for a pointer ladder that is).
After 3 years of WFP there are not many jobs that I can't do a top notch job on, but I would still not invite comment from customers, I TELL THEM what is best, I DIRECT their thinking...it's safer that way!!
