A billionaire enters a gas station. Seeing the "Leave a penny, take a penny" dish on the counter, he scoops up all of the coins and pockets them.

"I'm a genius," he says to the protesting clerk. "I earned this money. Anybody could have taken it, but only I had the vision to see what was possible."

@maxleibman when I was a student, and you can tell from the prices of coffee how long ago that was, I used to buy a cup of coffee at the station every morning on the way in to university. A black coffee cost £1, a coffee with milk cost £1.20. You'd pay at the counter and everyone no matter what they ordered got handed a black coffee, then you added your own milk from a jug by the door on your way out on an honesty system.

One morning a guy in a fancy suit pushed into line in front of me, which annoyed me enough to make me pay attention to him. He ordered and paid for a black coffee then added milk to it. And this guy singlehandedly taught me a lot about the sort of people running the world.

@afewbugs @maxleibman and now he's an exec at a water company! (I'm guessing)
