Many years ago i had an elderly customer call to complain about the cleaning job I did on her carpet. She called 5 months after I cleaned to tell me that if I had done a better job her 10 year old dog would not have continued to pee on her dining room carpet. She ask if I could take care of her problem, I told her yes for a nickel. When she ask what I could do for that price, I told her 22 shells were very inexpensive. She called my office later in the day to say that one of "our guys" needed sensitivity training, to which my wife agreed. 8)
