I once picked up several houses in an area where one of the blokes (an ex copper) was like the 'street leader'.
I knew if I didn't get him on board I probably wouldn't keep the rest of the elderly customers.
Anyway, this ex-copper was extremly anti-WFP; he even walked off when he came over to ask for a quote and saw my pole.
I offered to clean two windows for him as a demonstation; free; and if he liked the results he could take me on.
He obviously liked the job as he's been a brilliant customer ever since, and this street works out at nearly 40 quid an hour for Wor Lass and I.
PS.
This was quite a funny one for me, since when this ex-copper phoned me, he said the street where he lived hadn't seen their window cleaner for months and was after a window cleaner who didn't use 'the pole'.
I gave him Squeaky's telephone number and then went and canvassed the rest of the street, picking up eight customers in one fell swoop.
I told Squeaks, who called me a 'bugger' or something, so refused to go and do this one blokes account.
I'm a proper poop!
