So what's the deal?

I was on LAS-ORD flight this weekend. The FA came by with a tray of H2O and sparkling wine. I asked her for a Diet Coke. She said at 10,000 feet she would bring me one. I said that my last half-dozen flights the FA brought me one when requested. She said that is not policy. We had a "discussion" about that being policy or not. I thought that the tray was standard and you could request another beverage. She would not budge, so no DC for me. Were the other FAs who served me a DC going against policy?

I would like to know what the current policy is. Matthew or anyone else, please let us know.

And "service is our passion"? Sheesh.
