I hate those guys. I start getting confrontational when I see them squirreling around pairs, checking their phones, creating piles of shoes. Or they see you with a return and are hawkeyeing you. Last time I saw a dude doing that I started having bad thoughts
But Nike allows em to do what they do. Nike could easily put practices in place to stop it. They stopped allowing returns at outlet stores (not factory stores), so they could implement some policy to stifle resellers. But they don't.
