say you can and charge more for it as it is extra work, she may then stop asking, it is harder at this time of year as it takes ages for them to dry, I have not had this problem as yet, but I guess it will happen at one stage and this is the thing I would say to them if it was said to me.

i did consider telling her that it would take me another 20 minutes and would cost an extra tenner. But like i say, i'm still in the process of converting customers hook line and sinker to wfp and so i reluctantly trad no external piece of glass anymore.
There isn't a house on my round anymore that i haven't gone back hours later and checked repeatedly for spots and runs after the 1st clean. The last house i had to detail continued for 8 months before they poled up good using pure water only and that came good 6 months ago. I'm not stupid enough to realise i'm gonna leave a perfect job everytime, but i try, check until they're good and guarantee my work for 48 hours with all my customers knowing my full name, landline, mobile and address. I can't do more than that.
Anyway, introducing wfp was stressful for some customers

cos you'd say X and they'd hear Y. I had to refuse to use trad outside to get wfp accepted. It's no problem for people to accept it now.
I just get the occasional moment nowadays when someone thinks i am charging way too much, when all i am doing is my job very quickly. I value their custom for as long as it lasts but eventually they will have to learn to understand or they will go.
