The Power of Starbucks

[crew]

I'm at the Ft. Lauderdale airport waiting for my flight home.
I'm seated across from a Starbucks and, as I'm a little bored, I'm watching the line there. There are easily 50 people in line now! Not 100' away is a small bagel shop that also has coffee. They have 6 people in line.
Btw, the Starbucks line is very slow. It looks like a 15-20 minute wait. What does Starbucks put in their coffee that make people crave it so badly?
In the interest of full disclosure, I'm drinking a cup of their coffee now and loving it. I'm with my partner and she waited in the Starbucks line while I got us bagels in the other line. (As I said, I'm a little bored and felt the need to share this useless information)
