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.
