At the coffeeshop, I order two cups of iced coffee for takeout. The waitress asks if I prefer she put them into a carton holder or a plastic bag.
I answer "carton holder" (probably because it's recyclable).
I am reminded of Don't Make Me Think.
Great apps let users accomplish tasks easily, directly. Coffeeshops should too! Don't complicate the order. Don't ask me! Instead, design a better takeout container.
