As the teen began to walk away, Diaz told him, "Hey, wait a minute. You forgot something. If you're going to be robbing people for the rest of the night, you might as well take my coat to keep you warm."

The would-be robber looked at his would-be victim, "like what's going on here?" Diaz says. "He asked me, 'Why are you doing this?'"

Diaz replied: "If you're willing to risk your freedom for a few dollars, then I guess you must really need the money. I mean, all I wanted to do was get dinner and if you really want to join me ... hey, you're more than welcome.

"You know, I just felt maybe he really needs help," Diaz says.

Diaz says he and the teen went into the diner and sat in a booth.
