I thought Ya'll might like to see the way this guy has his sales set up. He does landscape work and sells on the side among other things. I met him a few years ago and see him every year at the Day Lily festival. Here's his facebook page of what he sells/does but more importantly for some of you might be the way he collects money when he's not home. He has a store set up on Square. I'm sure he has some theft, I know he's not in the best part of town.
