I have had a few classics. I was just starting one job when the customer asked if I would clean his car? I said thanks, but no and he said "but I have just driven all the way from Newcastle" ?
Another had watched me clean a house over the street from him {wfp} and asked me to do his. I started to clean and he came out and said what are you doing? Er, washing the windows as you asked me to. "Don't be ridiculous" he said and slammed the door. Needless to say I didn't finish the first window before packing up.
