franky.
did you just do it or did you tell them all this was going to happen??
just turned up aqnd done them,and explained how it worked,
lost one after 6mths of cleaning here windows wfp.her reason quote was"they are clean but i dont like them left wet" donttttttttttttttt.....................................
pior to that she was a custy for 5years.
as with truning custys down if cant be done wfp,i really take a good look at the job,and weigh up the options,ie is it worth it getting ladders out etc,before passing it on.
and yes i do have a load of work for the 2 of us.
