PDX Stop and Shop (or Just Look)

K, we're going to, at the very least, Mercantile (729 SW Alder) and Mink (3418 SE Hawthorne Blvd). Even if we don't buy anything, I need to look. So do some light cleaning in the SUV. We're also going to wear lots of makeup, as if we were retail sales associates. Why do SA's wear so much makeup?
