Do it yourself milk

At the Cosi in Bryn Mawr, they have only half & half and nonfat milk. So someone like me who likes regular (or even 2%) milk in their coffee has to act like a chemist.

The other mystery here is that there's a display case full of muffins but if you ask for one they go and take one out of the refrigerator and microwave it to bring it to room temperature. The net effect of this is to make a coffee and a muffin transaction into something complicated and time-consuming.
