i do tops and bottoms trad, on sat new round a customer said if you are going to use that dont bother she said she was fed up of her previous cleaner leaving her walls and path wet, , had a couple, this usually happens on new rounds where people are not use to you. none of my old customers complain, except one with new leaded windows. i have no bad customers thankfully. you have to give and take a bit, this time of year is different with the water drips turning to ice on there fronts if too cold, you will get a lot of comments saying dump.
