most windys custys would like you only turn up when the sun is out but it aint being realistic,its rained most days in the past month round my way and for most parts of the country,but its tough i dont clean windows in the rain either (im trad),but its mainly showers so sit in the van and get out when its stops if you only do half a day but you have been out for 8 hours at least you earned some money,custys have said to me before its pointless when the weathers bad but i still turn up and they dont say owt,you need be out in all weathers to make a living
