personally im going to give it a whirl regardless, i know if my pipes in the van are up to scratch and not frozen up and if i keep the stream up to a high enough setting i can carry on regardless, i have targets to meet and i also have to get new customers aswell this month regardless of the weather, windows still get dirty imo. If i cant get out from wed on this week ill write it off and try again from next monday, but we have to at least try i feel, customers look at you better if you try and get out in all weathers i feel.
