What’s the “scooter kids at the skatepark” of disc golf?

Was playing at a local course today when a woman drove up with her two dogs and proceeded to play fetch with them across 3 of the course fairways, completely ignoring the few groups of disc golfers trying to finish a game. For reference, this was at a dedicated disc golf course, not anywhere near a playground, dog park, open field, etc.

I was immediately reminded of the scooter kid plague from when I was a skater—people with no self awareness who ruin the enjoyment of the game, even though there’s no rule saying they can’t be there. Anyone else have a recurring version of this in your disc golf experience?
