«These sugar-free ones? How are they sweetened?» «Fake sugar.» heehee. The girl at the counter did actually know what sweetener they use. Placed had like 10,000 choices for their Premium frozen yogurt. It’s premium, so you know it’s good. Plus there were like 100,000 choices for toppings. Shiz adds up pretty quick tho when you pour your own premium froyo and scoop up all yer toppings when you pay per ounce.
