Why do customers not want us to access the back when they are not in? The only answer I can see is that they don't trust us around the back of their house.
My view is that, if they cannot trust me, I cannot trust them, and therefore I have dropped a number in the past.
This last week one lady who I dropped for this, came back to me and asked if I would take her back on. She had asked her next door neighbour to tell me not to do the back because she was on holiday.
I explained to her that my name and integrity are very important to me, and that her neighbour would obviously conclude that I was not a trustworthy person, because of her actions.
After 25 years of cleaning windows, and 20 years on this particular estate, having customers treat you as though you are a burglar does not put them in my good books, and so I now tell them so.
