The drinks are advertised as being a certain number of ounces, we just see small, medium and large, but if you actually check the calorie counts it is in ounces. It has been autofill as long as I can remember around here, so I just figure before it was autofill I was getting more than advertised and now I am only getting what I pay for. Besides I think the giant cup of sweet tea for $1 is a good deal and it stays cool in that cup and lasts all day. I guess if economy was the real issue for me, I wouldn't be buying my soft drinks at McD and would be bringing home 2L on sale all the time.
Now lets talk about the Starbucks that costs more than gold! LOL
