I once kept getting calls from a home siding company; the person would say that a representative had been in the neighborhood and noted that my house really was in need of siding. I would patiently tell them that I already had siding on the house and it was only a couple of years old. I still kept receiving calls. Finally I made an appointment with them for the representative to come out and talk to me. When he showed up at my door, he had a very puzzled look on his face and said, "Ma'am, you already have siding on your house. Why did you make an appointment? You are wasting my time!" I told him his company had wasted my time for the last year calling me and I had told them I already had siding so I thought I would just waste some of their time! I never got another call from that company.
