I do both and find its most important to get to know
Customer then sell the wfp as a superior method of cleaning.
" why would you invest £2000 in a cleaning system that doesn't
Work when you can use scrim and blade for £20"
One they realise that, they work with you to iron out the
Problem windows. This is what's happened to me.
Occasionally you'll be the idiots but be polite and replace them
With another job that's more wfp friendly.
