I once accidentally canvassed one of my own customers.
Worst thing about it was that I almost got the job!!
One evening I was canvassing all the ones I don't do in the street and must have got distracted, jotting down stuff in my notebook as I walked up the drive of this house.
Lady answers the door (never recognised her because I she was never in when I cleaned them and always sent a cheque) and I gave her the usual canvassing speel, when she replies, "
well I do have a window cleaner but he's too expensive,"
"
£12 he charged me just for the fronts!"
"
Oooh that does sound a bit steep" I said stepping back to take a look at the fronts......"
ah, oh....er hang on a minute"
(To be fair, I charged £6 for the fonts actually and had put a bill through for £12 because they had had work done and the windows were covered in cement, every one needing to be scraped. Since they were never in I just did the work and thought they would have understood why the price was higher that time).
