Do they sell fruit? Sure, if you want to spend $5+ and also get some cheese & crackers. It's hard to walk in hungry and walk out with an unsweetened iced tea. But I'm here to tell you it can be done - easier if I stop at the grocery store for some snacking fruit like grapes first. (damn, I mean praise those Chileans who send their grapes to my supermarket in March!)
Some "greener" choices at Starbucks that feel like a treat? Iced passion tea. A fancy Clover brew with a little milk. And maybe some grapes from down the street.
