I happened to be in my local store on Saturday night and was told in a very forceful tone "well, that's the last time you'll be able to use that discount!" Of course, I knew otherwise (thanks, Terry S) and didn't press the issue. But this is the same location at which I've had to fight for the discount in the past, so it didn't surprise me. I've only used the discount 5 or 6 times, but can only think of one occasion when I didn't have to explain why I was flashing my DVC Member card and wait for another CM to be called over.
Sheesh. You'd think the discount was coming off of someone's paycheck!!!
