Back in the eighties I had an auto salvage on a major divided four lane highway, named Louisiana 1 for a reason. Years later I-49 took most of the traffic and England Air Force Base closed but being on a little four mile stretch between the air base and the largest city in central Louisiana I got a lot of business . . . and a lot of salesmen wasting my time!
A good friend was retired but had a largely inactive salvage yard hidden on a hill in the piney woods behind his house on a two lane twelve or fifteen miles away. Walter did almost no business and got few visitors. I decided that he needed more visitors! Salespeople came by to sell me anything from pens and coffee cups to oil drilling rigs and gold mines, literally. When they showed up I'd get a thoughtful look on my face. "I don't need (whatever) but Walter was telling me just the other day he was looking for that." I sent a dozen or so salesmen a week to Walter. Visiting him a few times a week he would tell me, "never saw so many salesmen on the road in my whole life, can't see how they can all make a living!" It was a great way to get rid of pushy sales people wasting my time and a fine prank to play on Walter that kept him a little more active and engaged with people. Never gave a thought that it might be a little rough on salesmen.
This went on for six months or so. One day a salesman came in my place. "No I don't need one but Walter up in Tioga was telling me just the other day he was hunting one."
"#^*&(^)&(*^(^!!!!, he was the one that sent me to you!"
I went inside laughing and told my wife game over, Walter had figured it out.
RIP my old friend and beer drinking buddy.
