It will make you feel even more safe when you see how all those beverages and bottles that you are allowed to purchase on the other side of the checkpoint are screened... Some concession employee rolls a big cart full of the stuff up to the check point and one of the blue-shirt's finest does a cursory "looksie" at the cart and then the badged concession guy is waved thru in most cases. Ocassionally, I've seen cases of drinks pass through the screening belt -- but then that raises the question, "If the cases of bottles to be sold on the other side can pass through the sreening machine -- why can't the bottle that I bought on the unsterile side that I've been drinking from pass through the same belt?" Makes no sense, does it?
