A new one for me, finished windows on customers today wfp that is, crossed the street started on neighbours house and in reflection of window I can see him hoovering all downstairs windows with karcher thingy, was going to go back and explain he would be affecting quality of clean, but he's not a moaning type good as gold paid up made us a brew when I did them, so I smiled to myself and carried on, anyone else had this, prob say something next time or wait till he says there are marks on the windows and I'll say yeh you plant pot you did them
