The employees there need to be retrained in their jobs and given lessons in basic business behavior. The absolute worst experience I've ever had in a rental car place, was right there at that same Enterprise on Asheville Highway in Spartanburg, SC. If you can make it anywhere else, I would suggest driving or hitching a ride there instead. My $0.02.
Perhaps there is a key drop box. You could return your car and place keys in box.
They are closed Saturday from noon until Monday at 9AM.
