i would be polite and say to them "for now i will take you of my list and you can just give me a ring when you need me next" who knows..they may phone when they can have you regular again, or if they ARE trying to get rid of you then its easier for them, and less embarrasing for you this way. and there is always another customer round the corner to get
I like this one, it gets you out of sounding rude and it makes things easier for the customer.
I do have a couple of customers where you know that money is tight for them, every penny counts, and sometimes they simply cannot afford to have the windows cleaned even if they really want them done, so I am usually sympathetic to their situation.
But I will certainly use Dennis's solution on persistant 'not this time'ers'.
Oh, and if they say, 'Nah, no thanks mate, not worth it, its going to rain'.
Well that will be the last time I call, I won't discuss it with them, just smile and walk away...never to return
If they collar me in the street some months later and ask why I haven't been around I find it easy to tell them I don't do 'if in' work, which is what it the comes down to if you have a customer that continually looks at the sky and uses his or her judgment as to whether or not it is window cleaning weather...
