Whenever you enter any country, including and especially your own, you should expect that you are subject to inspection of everything, including your physical person, even if it isn't through a device that plugs into a wall. You should also expect that you and your luggage will have been sniffed by canine devices, both before (with respect to luggage), and sometimes, in your presence. (S)he is the fool who travels not expecting these possibilities, notwithstanding the odds posted on an IBB.

The Argentine canine authorities are particularly adept at the scent of US$ cash.
