Well heck, I just want to block the darned signals from my reptile building. I have employees who are apparently addicted to text messaging and that sort of crap and sneak the things in their pockets even though we tell them to leave the cell phones out in their vehicles.
As for an emergency in Walmart, heck most of the people wouldn't even notice it because THEY would be to preoccupied with yacking it up on their cell phones....
