On 06282023, at about 1830 hours, my family and I stayed at the Midland SD KOA campground. Our grill, that we brought with us, was not working so we lit the grill at a nearby empty patio site. A lady employee informed us that the grill was not for us to use and we apologized but she gave us permission to use the grill. A male employee came over to use and acussed us of stealing and cussed, he actually used cuss words, us out. Maybe we should have known better than to have attempted to use the grill but to have family cussed at is unprofessional and wrong.
