So I'm coming out of Walmart with my family. As we are heading to our truck, this woman takes her finger and draws a half circle (about 3-4 inches). I was only 15-20 away. Well, it pissed me off immediately. Vehicle is dirty...drawing on a dirty vehicle WILL scratch clear coat. My wife said why don't you say something. Her and her companion were probably 100 feet away by now. I get in my truck, drive up to where they were putting bags in the car. I parked, got out and said "Excuse me ma'am, I just wanted to let you know that when you draw/rub your fingers across a dirty vehicle it scratches the clear coat. She looked at me confused. Tried denying it at first, then I told her I was behind her when she did it. She then said, "I only touched it like this" and I told her that it wasn't just a fingerprint touch....I again tried to tell her that it WILL cause harm to the clearcoat. She says, I told him (her companion) that I liked that color. I told her thank you, but you don't have to touch a vehicle to think it looks nice. I explained that I spend to much time on it to have someone mess it up, even if it is unintenional. She then started loosing it. I told her if she was spending 35K for a vehicle, and she cared about her purchase, she would probably feel different. She said, "You are ridiculous, and insane". I told her that I don't see anything ridiculous about it and furthermore why does she feel the need to touch something that doesn't belong to her. I started out extremely polite, but then she turned into a beotch about it. She made it seem that I had no right to confront her about touching my vehicle and that I was in the wrong...I wanted to put my foot in her $%^....Has anyone else ever experienced this? Did I over react? Should I not said anything?
