Many years ago when we street raced alot we would cruise and park waiting for a race. There was this goober that hung around and he actually opened the hood of my Road Runner when I was talking to some friends, which instigated a very candid conversation about touching my car. A few weeks later, we were parked at the same place and my friends and I walked across the street to get a soda, upon returning the same idiot had my hood open leaning on the core support showing some people my engine. I promptly walked up behind him and slammed the hood shut on his hands- no issues after that. Couldn't do that now, you would go to jail.
More recently, we were at a cruise in and this guy walks up with his wife looking at my car, opens the drivers door and sits down in the car! I asked him WTF he was doing and he calmly replies that he was curious about my car and wanted to look inside. I asked him how he would feel if I was curious about his wife's boobs and asked her to open her shirt for a look inside. They left after that.
