i have been asked this twice by customers who have a trad guy
i have said if you want me to, ask your window cleaner to ask me
he has asked me to do 1 house, i do 1 window over a garage that he cannot get to ( i do both houses either side of the house ) i have no wish to take the job off him, karma and all that ( now i will hear the same rubbish, biz is biz and all that, but i treat others how i would like to be treated myself )
for the record i dont even charge for that 1 window, the home owner offered to pay me, but as its only 1 window and i do it from the drive way next door, its not worth me knocking on the door
