Same thing happened to me but using my new platinum card. Had just left he picking up my platinum card to go buy a new mattress I needed. Didn't even think about having it until the salesman asked if I was Emirates (was I that obvious? :-) Pulled out my shiny new platinum card and got a 2,300 Dirham discount. Figure I'm good for 5 years or so of monthly fees with it!
