If you order a trenta refresher or tea with no ice and use the shaker, not adding the ice gives you the perfect proportions for a grande. I wish they would re-label the shakers to account of no/light ice because normally you'd free pour to fill it up, but that messes with the proportions if they have more than 2 liquids (like a tea with half lemonade and half water) so the drink won't taste the same every time it's ordered. I just don't like my drinks to get watered down and the ice melts too fast where I live.
