SF dad grilled by park rangers over teaching tennis to his kids in a public park

A San Francisco father was approached by city park rangers while practicing tennis with his two children at Golden Gate Heights Park, who questioned whether he had a permit to teach tennis. He was warned he could face a $192 fine for teaching without a permit, though the encounter ended without a citation after his 6-year-old daughter told the rangers, “He’s my daddy.” The park service says officials routinely check public courts for commercial instruction, while the father argues parental instruction should be treated differently and hopes for a more family-friendly policy.
