I work differently to most on here, i.e. I work to a frequency that suits my customers, be it at 2, 4, 6, 8 or 12 weekly intervals. I also have others who phone me as and when they want a clean. It doesn't worry me in the slightest as long as I make enough money.
So if anyone wants to drop out for a few months, I just say 'no problem, give me a shout when you need me again'. I don't see the sense in turning away work if it's on offer and I can fit it in.
