Maybe not Mother of the Year material, but this technique certainly seems effective.
But really, I think this is a commentary on the speed of technological advancement and how it affects all our lives. 10 years ago, a mother could TOTALLY get away with dragging her small child by the neck through a Verizon store (or, I guess, back then, a Sam Goody or something). But now, with cell phone cameras and YouTube, it's just not doable any more. We're all going to need some time to adjust.
