The days when I don't work at Starbucks- which are unfortunately this summer going to outnumber the days I do work at Starbucks- I get stuck somewhere else in Target, typically cashiering, at service desk, or serving Icee's, hot dogs, and popcorn to mothers and children. Today was an Icee/hot dog/popcorn day, and quiet honestly there are only so many times you can pop popcorn before you run out of things to do. If you're talented, you can make the task last fifteen minutes. And that's if you're watching the kernels pop.
Obviously, a much better use of one's time would be doodling on pastry bags.
