There is a beautiful story named Jonathan’s Card listed on hacker news today. It is about an experiment on sharing a starbucks card – everybody can buy a coffee on this card, and everybody can also chip in if he wants. It has been interesting to see the balance up and down throughout the day.
Then there is an even more beautiful story on good infection.
My girlfriend and I were graduating from pharmacy school and she was applying for residency positions (yes, they have those for pharmacists). Well, she found out she got the one she really wanted and so that night we went out to a nice dinner to celebrate. We did it up like you would expect a happy couple to – nice bottle of wine, share an appetizer and dessert, etc. We were still living on loans at the time and so in my head I was keeping track of about how much the meal was going to run me at the end of the night (for better or worse – keep in mind we were in college at the time). We had easily cleared a hundred bucks (quite the meal for college students who usually eat $7 sandwiches or more likely cook for themselves!), and when it was time for the bill, our waitress told us “The couple that was sitting over there paid for it.”
And some people pay for bridge toll for more than just themselves.
