I saw a documentary on one of the news channels about this (either MSNBC or ID) the other day. They had the loss-prevention specialist from Walgreens on explaining the problem. In some areas all of the store's products are behind plexiglas and you have to have a clerk unlock it and hand you your items. Kind of harks back to the old general store days when you'd tell Old Clem behind the counter what you wanted and he'd hand it to you.
