So now what happens when bums steal the carts?

Will this nifty item tell them what alley to find their crack in? I never imagined there would come a time when anyone would need GPS technology to navigate their way through the grocery store. It actually might be kind of useful....like, for those times that you need to find chipotle peppers in adobo and suddenly no one at Publix speaks English anymore. I just can't imagine my dad using one. Somehow I don't see these arriving at my Publix anytime soon...
