thats funny,
ive only really drove past another guy using wfps, and seen others working in the same areas, you see so many other window cleaners about, or window cleaners 'vehicles' general ladders on the roof, bucket in the back estate cars, trying to dodge one another i bet their just as friendly as you are - but i wouldnt want to bump into any ''get out of my patch, this is my area F off!'' who threaten to give you beats. Oh well what can you do about it.
