Starbucks recently announced that it would be getting rid of straws by 2020. That’s great for the environment! They would probably be using a clear version of the lids that they use for the hot drinks. However, that works well with liquid drinks.
What about for those ice blended frappuccino? These drinks are “thick/heavy” similar to a milkshake consistency. I would think that a straw is required for these drinks.
