I agree with you mate on you reasoning for not giving him a qoute, but if he never told you he had a cleaner, and asked you to go by and give a qoute.
Would you have went?
You would I hope, so I would still do that, but put out of your mind the other cleaner, as the guys only trying to have you knock your price down.
Again not a loyal customer but if he want cheap he will get cheap. I dont think you would have been doing it for long, but if you have spare time in your schedule then why not, even if it is only for a while.
Not good for window cleaners, and he will end up with a very unproffesional window cleaner and an unreliable one if he continues to do that.
I do think you might have saved some hassell by not, he does sound like a time waster.
