For all you wfp users im sure you've been asked this question at some point. Ive got a customer that had a massive strop when I first went to do her house in slight drizzle and I remember being caught so off guard when she questioned me I didnt have much to respond with. Since ive taken her on ive never had this issue since as its been fine weather when she is due, now im due to do it tomorrow and its going to be overcast and showery down here so she wont be happy. Now when you tell your customers it doesnt make a difference to the quality of the clean if you do it in the rain what do you respond with when they say 'why? the rain is dirtying the window'
