I visit this location every time I visit Fredericksburg. Towards the end of 2023 it was primarily young adults who seemed to be running this thing. I was astounded by the maturity that was shown each time. Since then, a new group of adults have started running the place. The passion and ambition has deteriorated. I would love to see more mature young adults such as Karson. I'm not sure if he still works there, but he sure was a delight each time he was my carhop.
