The Concession stand modification was done to accommodate a Little League Baseball field, which didn't have the ability to build a permanent structure on site.  The also wanted to be able to securely lock up the unit so that no one could break into the unit.

The Counter top was removable and the window has a roll up security door, that locks from the inside of the container.  Shelving was used on the back wall for inventory. 

The container can be moved to other fields should the need arise for special tournaments or fund raisers.
