Re:What size lemonade?
As I answered you on your other thread, as well as I remember Bill served a 24 oz. size. You do have to realize, using the chunk (not shaved) ice, which is what Bill did, that a good portion of the cup will be ice. Since you live in the Tulsa area (and we have been hearing all about thye scorching heat you have been having this year) I would think your customers would welcome a large size drink. I would also think the larger size would be easier (or at least more of an attention getter) to shake.
