I can just see it now...thank you for lining up at immigration for an interminable amount of time, you get an extra stamp (I don't get them anymore-haven't for years) when you spend $100+ on women's lingerie, like the ones we men are modelling!!!

And then, after you pass immigration (or before on the way in) you MUST run the gauntlet of shelves...

BTW I heard that DFS sales have gone down since they ambushed departures and arrivals, people don't "see" or look for the shop so much any more. Not sure of the fact of it, but doesn't sound that surprising.

Now wouldn't that be good, one card to shop, immigrate/emmigrate, implanted chip, big brother...
