So I read today that a wonderful thing happened at a St. Petersburg, Florida Starbucks, where 457 consecutive customers paid for the drink order of the person behind them, thus creating a 10-hour “pay it forward” chain of good will and caffeine-filled creamy caramel macchiato happiness. It’s a sappy, syrupy (literally), feel-good story if one ever existed. Good for them. That sort of thing has never happened to me, but were I to find myself in the middle of such a sudden outbreak of outrageous open-handedness, I would gladly accept the offer of generosity from stranger-in-front-of-me. I mean, what kind of person turns down such a grand gesture? The real question is, though, would I be willing to keep the ball rolling? Would I dutifully fall in line to preserve the chain unbroken?
