I never realized it but I'm guilty of almost all of those.

Once I was riding along and about half a mile from home I saw a skinny, young man struggling to push a car through the intersection. His very pregnant wife was steering. I jumped off and helped him push it into the nearest drive, which happened to be a fire station. He said, "we ran out of gas." I told him I had some gas, I lived just down the street, and I would go get it. I came back in my truck with a can of gas. I pulled up next to his car and got out. Just as I got to his car, a fireman came out. He said to us, "You can't park there." I told him, "they ran out of gas. We'll have it out of here in a couple minutes." He barked back, "It's a federal offense. You can't park there!" Then turned around and walked back in. I thought to myself, "thanks for the help, prick."
