For a second job, I drive a water truck doing dust control on construction sites. It's basically a big water tank (2200 gallons) bolted onto a truck and has spray heads to put down the water.
One evening a lady waved at me to pull over and when I did she said I had broken her windshield with a rock from my truck. She claimed that had seen the rock fly up from the top of my truck and then hit her windshield.
So I said "You do realize my truck is just a big water tank, and we don't load or haul rocks AT ALL ? The only thing that ever goes in that tank is WATER."
She just stared at me with a blank stare, and then she starts in on me with "Well my husband is a cop, and you could be in alot of trouble!"
So I said "Did you just threaten me? You're threatening to have your husband, who is a police officer, to harass me? That seems like a pretty serious abuse of authority to me!"
She was seriously flustered at this point and started backpeddling... "No, I wasn't threatening you......"
It ended up that I gave her a business card with the company's info on it, But I never heard from her or her husband. Go figure.
