Free Starbucks?!?!

I was at Starbucks this evening picking up a much deserved Eggnog Decaf Latte for my wife for being gone most of the day today. I ran into a friend there. Talked to him for a while. Then I thought he was next in line and he let me go first. What a nice guy I was thinking to myself. So I ordered my drink. Pull out my card to pay for it. The Starbucks employee says "Oh, it has been taken care of." What? I stood there confused looking at the register wandering why it said $0.00. Well using every bit of intelligence that I had, I realized my friend paid for it. Wow! What a nice surprise. Puts me in a giving mood. Which is a good thing.
