My guest and I ordered the lean mango smoothies. I asked the cashier if it was made with yogurt and he said "that it could be.". I looked at my receipt later and discovered that he charged me an extra dollar for each smoothie for the yogurt. I guess this is my fault for not asking but I think it was up to him to advise me. The smoothies were okay but we would try something different next time because we both didn't finish ours.
