I have kulled a few this year when I switched over to WFP as they are such a pain in the arse and disrupt the flow of my business, my business comes first I'm affraid.
You have to harden up otherwise your business will suffer.
My new customers that I will gain in Essex will have a 3 strike rule and I will mark it down on the work list.
They will also be charged a minimum £10, even if they just want one window cleaned.
No messing about lol
