#67, Pick up the tab for the car behind me in line

I went to Starbuck this morning. I had a $15 gift card from my birthday that a friend gave me. Since there isn't a Starbucks convenient to where I live and work, I don't go very often. So I got my frappacino and coffee cake, and my total was $6.10. I was already debating using the rest for the car behind me - until the new, shiny SUV pulled behind me. I'll admit I was in a dilemma - and I judged... Someone with a nice, shiny SUV probably doesn't need their $5 coffee paid for. But then I thought "hey, maybe she's having a bad day" - you never know what's going on in someone's life. So I gave my gift card with the remaining $8.90 balance to the cashier, and said "Use it till it's gone" - so maybe the car behind me, and the car behind them had a little bit better day!
