DDE now tracking drink sales?

At Tusker House yesterday, my Disney Dining Experience (DDE) discount worked a little unusual (first: yes, counter service at DAK gives you a discount, because they don't yet have table service restaurants).

It used to be that the 20% discount was given on one line. But my receipt had two lines. One for DDE Food 20% - and then the amount saved.

The other line said DDE Drink 20% and listed zero as the amount saved.

Mind you, we bought a soda refill and milk, so we did have drinks. I conclude they are now trying to track how much money people are spending (and saving) by buying alcohol with the DDE.

Part of me is worried. Are they looking to curtail benefits? To charge more per year for the card? This bodes ill.
