We meet Russell, 19, the best mobile phone salesman in the mall — and possibly anywhere. His talent for sales is matched only by those of his girlfriend, Chandler, 18, a waitress.

Yes, some stores are going out of business in the Cool Springs Galleria, but it's just two stores. We talk to staff at one store that’s closing down, and at another, in the food court, where business is great.

A tale of two Santas. There's Tim Conaghan, a full-time professional Santa with a big belly and a real flowing white beard.

In a part of the mall no shoppers ever see, there's a snug, dark little room with 43 TV screens, one for each of the cameras in the hallways and parking lots, the roof and the loading dock. We hang out with the security people who work in there, seeing what they see.
