Airside at Keflavik. We had seen on the way in how much of a shopping mall the airport was, and also how smoothly operated passport control and customs were. Generally the country only works because of tourism and everything is arranged accordingly. But having passed by a bevy of duty free shops on the way to the gate we were still not quite prepared for the exit from passport control to North American destinations to be literally through yet another duty free shop. Just in case you somehow managed to still have any kronur in your wallet.
