Permissions for Setting up a Boiled Peanut Stand

by Leez Nuts

I mainly sell online, but I have a stand set-up, and am not sure about getting permission from property owners. How do the sellers here go about it? Are there any tips or tricks? Any no-nos?

I have a day job, so I can only sell on Saturdays, for now. When I reach a specific weekly threshold, SWMBO says I can quit the day job.
