I must walk through Atlanta’s Hartsfield International Airport 20 times a year. But I never noticed that booth vendors have no place to sit. That was before I read “Nickel and Dimed” by Barbara Ehrenreich. Now I have a new appreciation for working conditions of all sorts.

Take the woman selling sunglasses in the Atlanta airport the last time I was there. Sitting in a waiting area, I watched her for 30 minutes. She made no sales but merely stood calmly in front of her booth.
