There's some shops in my area for sunglasses, inside a large outdoor/sporting goods store (Cabellas). I did the sunglass store years ago in the mall which was a purchase and return. I'm not sure what to expect with it being inside a sporting goods store and looks like you are supposed to ask about prescription sunglasses.
Has anyone done these? Just curious what the report is like - I.E., requires a lot of details/heavy narrative or if this can be done as a more casual kind of interaction.
