I've been asked for ID several times when using my DDE card. The strangest place was at POP food court. I used my DDE card, gave the CM my room key to put the charge on...she asked to see a license! Ah, I don't carry it with me when going to the food court. I told her I didn't have it on me...why did she need it? Told me that it was in case the DDE had been stolen, along with the room key! Had that happen several times at POP. Only once or twice at other spots...but I just showed my license and they were fine.
