That maybe what some window cleaners say, I personally dont!
I once tried to say to my mortgage company sorry I cant pay my mortgage this month, weathers been a bit wet, they didn't have the slightest interest, hence my change of opinion!
Besides, lets be honest, clean a window in the rain, maybe your own window, then see when the rain stops the standard of the clean, it's just as good??
I read posting after posting of people on here complaining they are behind on their work, it's raining, no money etc.......well keep cleaning through the rainy days and perhaps there will be less postings of misery?
