CORRECT, DING, DING, DING, WE HAVE A WINNER.
A friend of mine is a manager at the local Walmart, where they recently removed the self checkout lanes and he told me it was because of thieves.
Even with all the video cams that they have, and everyone knows they are going on video, they still continue to steal.
Wal-Mart here yanked theirs. This in an upscale suburb.
