When traveling abroad, don't fall victim to thief's or pickpockets: arm yourself with a fake wallet placed in a deliberately more accessible location than your real wallet. Keep the real wallet tucked deep inside a coat or in your front pockets. The fake wallet can be crammed with coupons or paper to have an authentic shape and bulge. If the worst does happen, at least you'll have the last laugh knowing the thief will open a wallet full of Big Mac coupons.
