I get customers (mainly women) who have no idea what the wfp system is, Now and again they come out with some right classics, Today was 'that's a nifty brush' - doesn't even consider the whole van setup, remote control, pure water hose etc! Just feels the need to only praise the brush! The best one to date is this: 'thats good, you've got a stick thing now to clean the windows' Yes... A 'stick' thing... I mean what? A stick thing? Classic!! I go along with it now, 'Yep I can clean that window, I'll use my stick for it, no problem'
