It was a long time since I've been over to the G side AC at ORD. To my pleasant surprise I saw that they've installed a self-serve juice/soda machine there (could've been there a year ago but I wouldn't know ) ^

I think more ACs would be better off installing these self-serve machines, especially at the more busier ACs like LAX and JFK. It's a hassle to ask the bar attendant for a free cup of Coke/Sprite/whatever.
