An Appropriate Reaction
About four years ago, at a gas station, I watched two cars slowly back into each other while backing out of their spaces in opposite curves. No biggie, just exchange cards and be on your way, right? Nope.
One of the two drivers decided this would be an appropriate time to go inside the store, buy a two-liter (0.44 gallon) bottle of Diet Coke and a pack of Mentos, hose down the other car with foam in his anger, then drive off.
After I was finished laughing myself blue, I stayed to help the other lady talk to the authorities. Story credit: Reddit / SweaterZach
