As regards the water. I think it is pretty bad form to take water from the custy's tap, especially with out asking. It doesn't look very professional either.
It is funny though as in reality there isn't a lot of difference between say a gardener using an outside tap and us, we both provide a service the customer will reap the benefits of the water usage. I suppose the difference between a gardener is that he doesn't carry a massive baffled tank with him.
In reality though it doesn't look very professional and could be seen to be taking a liberty as in this case.
Squeeky are you producing your own water yet or still getting it off of Mr Giles?
Simon.
As for the other stuff, it doesn't really matter how much you earn, or whether you are expensive or cheap, as long as you provide for your family and are happy in the job.
