Is this a job or a business, do you want good customers or the ones that drop you as soon as a cheaper person comes along.
My domestic customers know I don't mess them around and expct the same in return.
I could'nt send my workers out knowing Mrs Grumpy at No52 might not want them doing, I have had some say they got no money or away on holiday which I can understand, but if I was dropped for cheaper, the trust has gone.
We are trusted to provide a good regular service and the customer is trusted to pay for it.
Commercial is a whole different ballgame
It takes a few years to get a good solid round.
There is millions and millions of windows out there, go get.
For those who get messed about and think it's fine here's a link for them
