I call this my girl scout cookie table. I created this one bench version of my picnic table for vendors, yard-sales, and flea markets. It's also great when you need space for a separate bench or wheelchair.
As a vendor you need a place to sit down, and a clean side for customers, this table provides that.
You can sit on one side of the table comfortably, and display your cookies on the other.
