Disrespect at a car show.
I saw a couple of beer drinking men point out a 6 pack carb linkage on a show car (owner not around) and proceeded to cycle it a few times to watch how it worked. They must have cycled it 5-6 times watching the linkage move. I straight up asked them when they were going to start it. They spun around and looked at me with a half sober smile and shuffled away. I told the guy sitting behind the next car and he shook his head and told me the owner just walked away to take a leak.
