so a slow-moving couple enter the starbucks in front of me, and the woman, wearing a calf-length down jacket, who moves a little jerkily, and resembles what the New York Press used to call a skel, reaches down, grabs a Starbucks sandwich, and pockets it. They loiter another minute, and the dude asks her, sotto voce, "Do you want a coffee?" And then they leave.

What should I have done?
