The duty-free cart rumbles down the aisle of your international flight, packed with perfumes and liquor, watches, RFID  (Radio Frequency IDentification) safe wallets, adapters and other travel must-haves. The cabin crew manning the cart look hopefully left and right and if it's anything like a typical flight, the cart gets to the end of the cabin without making a single sale.
