No kidding? I assumed they were pretty closely monitored. I would think there would be an alarm if not paid pretty quickly. The are a ways from the exit to provide time for security to make a move around here.
What kills me is seeing people come to the self checkout with shopping carts overfilled with items who then spend the next half hour checking out. The self checkout is for folks with 10, maybe 15 items tops. There's no way for store personnel to know if people with full carts are paying for everything unless they stand there and watch them, and the meantime countless other people are walking out with items not paid for. It's crazy.
